Effect of Adsorption or Electro-Adsorption of Electrolyte Components at Interfaces on the Electrochemical Performances of Li-Ion Batteries and Supercapacitors
Authors: Lemordant Daniel , Zhang Wanjie , Ghamouss Fouad , Dahbi Mouad , Raymondo-Pinero Encarnacion , Anouti Mérièm
Published: February 2020

Electrolytes of relevance for high performance Li-ion batteries have to fulfill a variety of criteria such as a high conductivity and phase stability in a wide range of temperatures, a large electrochemical window and high Li+ transference number across interfaces to reduce interfacial resistances and anion concentration polarization. Beyond that, electrolytes should wet separators and electrodes, which is particularly crucial if nano-structured electrodes are used. From this point of view, liquid electrolytes present some advantages over solid or gel electrolytes. Finally the electrolyte must be not too costly or environmentally problematic. Owing to their strong dipolar moment cyclic alkyl carbonates, sulfones and nitriles exhibit high surface tensions which make them unsuitable for wetting polyolefin separators. Another consequence of the use of highly polar solvents is that there are preferentially adsorbed at charged interface and hence, the composition of the adsorbed film will be different from the bulk when binary mixtures of solvent are used, generally composed of a polar and non-polar solvent. As an example, the oxidation potentials of binary solvent electrolytes at the LMNO/electrolyte interface do not depend in a simple manner on the composition of the mixture. Moreover, in order to improve the stability of interfaces, film forming additives, such as vinylene carbonate (VC) or fluoro-alkylcarbonate (FEC), are usually added in small quantities. These additives will compete with the solvent molecules and electrolyte ions, solvated or not, for adsorption at the electrode surface. Hence, it is not surprising to find that the reduction potential of such additives varies strongly with the composition of the electrolyte or even with the addition of a second additive. Given examples will concern the electrochemical performances of TiSnSb conversion active material in the presence of VC and FEC as additives in a mixtures of alkyl carbonates. Other examples will concern the performances of positive active carbon electrodes, designed for use in Li-ion supercapacitors, in order to enlighten the role of solvation on ion electroadsorption in small pores.

Published: February 2020

A group of electrolyte additives are selected for high voltage lithium ion batteries based on the concepts that the additives are oxidized preferably to solvents and subsequently protective films can be formed on cathodes. The oxidation probability of the selected additive is understood with theoretical calculations and their influences on cathode performances of high voltage lithium ion battery are investigated via physical and electrochemical characterizations. The selected additives involve the molecules that contain aromatic ring, sulfur, phosphor, nitrogen and or fluorine. The cathode materials that the selected additives are used for include spinel nickel manganese oxide, layer nickel, cobalt and manganese oxides and layered lithium-rich manganese oxide. The effects of the selected additives on graphite anode are also considered.
Co-Sinterable Lithium Garnet-Type Oxide Electrolyte with Cathode for All-Solid-State Lithium Ion Battery
Authors: Ohta Shingo , Kihira Yuki , Asaoka Takahiko
Published: February 2020

Lithium ion secondary batteries have been widely used as power sources for electric vehicle (EV), a mobile phone and etc., and are now indispensable for our daily lives.At the same time, safety of the batteries has been becoming an important issue with the progress of their performance, which recently motivated the researches on all-solid-state lithium ion batteries using solid electrolytes due to non-use of flammable organic liquid electrolytes. Especially, increasing attention has been paid to the use of garnet-type metal oxides (e.g. Li7La3Zr2O12 (LLZO) and its derivatives) as a solid electrolyte due to not only good chemical stability and high lithium ion conductivity but also the potential to construct a bi-polar structure for high capacity by a simple co-sintering process. However, it has been quite difficult to suppress chemical reactions of the electrolyte with an electrolyte during co-sintering, and it is now one of the most important issues to significantly lower the sintering temperature of the electrolyte.

We investigated the development of a novel garnet-type oxide electrolyte, which is co-sinterable with a LiCoO2 cathode, based on the strategy to enhance interdiffusion between LLZO grains and grain boundariesby an appropriate selection of dopants in LLZO and additives. The sintering temperature of LLZO drastically decreased to 790 oC with maintaining high lithium ion conductivity but without the reaction with a metal oxide cathode (LiCoO2).

In addition, an all-solid-state lithium ion battery was successfully prepared by co-sintering of the stacked cathode/electrolyte layer, and confirmed to function well as a secondary battery. These results opened the potential for fabrication of all-solid-state lithium ion batteries using oxide electrolytes by a simple and well-established co-sintering process.
Behaviors and Energy States of Photogenerated Charge Carriers on Pt or CoOx Loaded LaTiO2n Photocatalysts Studied By Time-Resolved Absorption Spectroscopy
Authors: Yamakata Akira , Kawaguchi Masayuki , Kubota Jun , Domen Kazunari
Published: February 2020

For the development of highly efficient photocatalysts, energy states as well as the behaviors of photogenerated charge carriers should be elucidated. Femtosecond to second time-resolved visible to mid-IR absorption spectroscopy is useful to investigate the matters, therefore we applied this method to study the role of cocatalysts loaded on visible-light responsible LaTiO2N photocatalyst: this catalyst has poor activity for H2 evolution but highest activity for O2 evolution when CoOx was loaded. Time-resolved absorption study revealed that most of the electrons are trapped in the mid-gap states, created below 0.74 eV (6000 cm-1) from the conduction band. As a result, the number of free electrons giving the transient absorption below 2000 cm-1 was much smaller than that of the trapped electrons. When Pt was loaded, the electrons were captured by Pt and the lifetime of the holes (which give the absorption band at 17000 cm-1) became longer, however these processes proceeded at tens of microseconds and the efficiency was not high enough. On the contrary, the CoOx-loading resulted in the capture of holes within a few ps, and drastically elongated the lifetime of electrons to second region. Additionally, the depth of the electron trap became shallower from 0.74 eV (6000 cm-1) to 0.49 eV (4000 cm-1), suggesting the reactivity of the trapped electrons becomes higher. These perturbations to the electrons and holes are responsible for the increase of the photocatalytic activities. We expected that co-loading of Pt and CoOx further increased the activities but the recombination was accelerated.
Tuning Energy Band and Local Crystal Structure of Photocatalysts By Doping
Authors: Zhang Junying , Li Min , Wu Nick
Published: February 2020

The energy band configuration is a critical factor that governs the photocatalytic activity of semiconductors. Elemental doping of semiconductors could introduce the local states in the mid-gap or shift the conduction band minimum and/or the valence band maximum. Therefore, doping can modulate the light absorption spectra and alter the photocatalytic activity. We have studied the effects of different doping strategies on the energy band configuration, the local crystal structure and the photocatalytic activity in different semiconductors such as TiO2, AgTaO3, Bi2O3 and La2Ti2O7using the first-principle calculation. It has been found that isovalent mono-doping leads to slightly tuning of the energy band configuration and the local crystal structure. Aliovalent mono-doping usually induces the localized energy bands in the forbidden gap, which often reduces the photocatalytic activity. Compensated co-doping is an effective approach to improve the photocatalytic activity via narrowing the band gap without generating the localized energy band.

Generation and Injection of Hot Plasmonic Electrons from Optically-Excited Metal Nanocrystals for Photocatalysis and Solar Energy Applications
Authors: Govorov Alexander , Zhang Hui , Gun'ko Iouri
Published: February 2020

We investigate the effect of plasmon-assisted carrier injection from metal nanocrystals to a semiconductor contact or to adsorbed molecules. We treat the problem of optically-driven metal nanocrystal using the quantum approach of equation of motion of density matrix. The energy distribution of optically-excited plasmonic carriers is very different in metal nanocrystals with large and small sizes. In large nanocrystals, most excited carriers have very small energies and the electron distribution resembles the case of a plasmon wave in bulk. For gold nanocrystal with smaller sizes (less than 20nm), the energy distribution of hot carriers becomes flat and has a large number of carriers with high energy [1-3]. Therefore, smaller nanocrystals are preferable for injection of plasmonic carriers into semiconductors or into molecules on the surface. The physical reason for the above behavior is non-conservation of momentum in a nanocrystal. The geometry, type of metal, and orientation of the external electric field are important to obtain high quantum efficiencies of generation and injection of plasmonic electrons [2,3]. Other important properties and limitations: (1) intra-band transitions are preferable for generation of energetic electrons and dominate the absorption for relatively long wavelengths (approximately >600 nm), (2) inter-band transitions efficiently generate energetic holes and (3) the carrier-generation and absorption spectra can be significantly different [2,3]. The results obtained in this study can be used to design a variety of plasmonic nanodevices based on hot electron injection for photo-catalysis, light-harvesting, and solar cells.

Interfacial Engineering for Efficient Solar Water Splitting
Authors: Vayssieres Lionel
Published: February 2020

With climate change seriously endangering our environment, security and health, the expected shortening in fossil fuels and sharp increase in energy demand from emerging countries, a substantial worldwide renewed interest in the field of materials for solar energy conversion has occurred within the last few years. However the high cost of energy production and relatively low efficiency of currently used systems pose an intrinsic limitation. (R)evolutionary materials development is required to achieve the necessary dramatic increases in power generation and conversion efficiency and so at low cost and large scale.

A general strategy for the modeling, design and fabrication of low cost metal oxide heteronanostructures consisting of quantum dots and oriented quantum rods-based large bandgap semiconductor structures and devices by low cost aqueous chemical growth will be demonstrated.

Synchrotron-based x-ray spectroscopies studies along with DFT calculation have been carried out to probe and engineer the interfacial electronic structure, confinement effects and orbital character and symmetry of the band edges and bandgaps as well as surface chemistry of advanced oxide heteronanostructures. The results reveal important fundamental and applied knowledge of direct relevance for semiconductor technologies such as photovoltaics and photocatalysis. Structure-property relationships as well as efficiency optimization of novel low cost nanodevices based on quantum-confined metal oxide nanostructures and heterostructures for renewable hydrogen generation from seawater splitting as well as other devices will be presented.
Nanostructured Water Splitting Photocatalysts
Authors: Osterloh Frank E.
Published: February 2020

Photocatalytic water splitting with colloidal suspensions is conceptually the most simple and inexpensive pathway to hydrogen fuel from solar energy. Nanoscaling is widely considered to improve the efficiency of such catalysts, but as a detailed analysis shows, nanostructures also have considerable disadvantages. Using recent examples from this laboratory, this talk discusses the effects of nanostructuring on carrier generation, separation, and recombination, as well as the possibility of controlling nanostructure energetics and reactivity via potential determining ions and quantum size effects. The use of Surface Photovoltage Spectroscopy to probe photochemical charge separation on the nanoscale is also discussed.
Toward Efficient Photocatalytic Materials
Authors: Feng Pingyun
Published: February 2020

The current dependency on non-renewable and polluting fossil fuels is responsible for many social, environmental, and health problems such as air pollution and greenhouse effects. Furthermore, the limited supply of fossil fuels is unable to meet the world increasing energy demand. It is therefore essential that alternative means of generating energy and fuels be developed. Of all alternatives, conversion of solar energy to chemical fuels or electricity is one of the most attractive routes because of the unlimited supply and easy accessibility of sunlight. In this talk, I will focus on our efforts in the synthesis and characterization of visible-light responsive photocatalytic materials. Several families of materials with visible light response have been synthesized and their photocatalytic properties have been characterized. We have not only made progress on the development of new photocatalytic materials with novel chemical compositions but also succeeded in improving the band structures and morphologies of well-known photocatalytic materials for water reduction or oxidation.
Wide Bandgap Copper Chalcopyrite Materials for Photoelectrochemical Hydrogen Production
Authors: Gaillard Nicolas
Published: February 2020

Photoelectrochemistry (PEC) is one of the most efficient methods to produce alternative fuels, although the efficiency, cost, and durability of lab-scale systems are currently not at the level required to make this technology economically feasible. The chalcopyrite material class, typically identified by its most popular alloy Cu(In,Ga)Se2, provides exceptionally good candidates to meet the requirements identified for cheap, sustainable solar fuels production. As we recently reported[1], co-evaporated 1.6 eV CuGaSe2 offers very high-saturated photocurrent densities (-16 mA.cm-

2 in 0.5M H2SO4 under AM1.5G illumination), long durability (up to 400 hours), and high Faradaic efficiency (>85% for non-catalyzed systems). Although CuGaSe2 has the highest bandgap of the copper chalcopyrite class, its optical characteristics are still too close to that of amorphous silicon (a-Si), a low-cost material our research team has identified as an ideal photovoltaic driverin a monolithic hybrid photoelectrode device. Nevertheless, a solar-to-hydrogen efficiency of 3.7% was achieved using a co-planar integration scheme. In order to improve the water-splitting efficiency further, novel chalcopyrite alloys with bandgap greater than 1.6 eV must be developed.

In the present communication, we report on our efforts to synthesize 1.8-2.2 eV band-gap chalcopyrite materials for PEC water splitting. Specifically, we investigated the effect of sulfur on the optical and photoelectrochemical characteristics of the copper chalcopyrite material class. Using co-evaporated 1 μm-thick CuGaSe2 as baseline system, we demonstrate that the substitution of selenium with sulfur is accomplished through a simple annealing step. As a result, a dramatic change in optical properties was observed, with a bandgap increase from 1.6 eV (CuGaSe2) to 2.4 eV (CuGaS2), in good agreement with theoretical predictions[2]. Then, by simply adjusting the indium content in the film during the initial growth process, the bandgap of sulfurized copper chalcopyrite was decreased from 2.4 eV [GGI=Ga/(Ga+In)=1] to 2.2 eV (GGI»0.8) and finally to 2.0 eV (GGI»0.7). X-ray diffraction data indicated successful bulk sulfurization by the shift of the prominent (112), (220), and (312) reflections to higher angles. Preliminary PEC analyses revealed an anodic shift of the flatband potential with increasing bandgap when compared to CuGaSe2. This suggests that the bandgap modification in sulfurized films primarily stems from a downward shift of the valence band, an ideal situation for p-type PEC systems. Saturated photocurrent densities greater than -5 mA/cm2 were achieved with 2.0 eV red CuIn0.3Ga0.7S2 photocathodes in 0.5M H2SO4 under AM1.5G simulated illumination.

Solar Fuel Production By Plasmonic Photocatalysts
Authors: Bright Joeseph , Li Jiangtian , Cushing Scott Kevin , Wu Nick
Published: February 2020

As the world’s energy demand increases and the finite supply of fossil fuels is used, clean, renewable energy alternatives are needed to fill the void of fossil fuels for supplying the world’s energy. One potential alternative to fossil fuels is chemical fuels produced through photocatalysis. However, the photocatalyst materials currently used and studied have problems such as poor charge carrier mobility and excitation lifetimes, large bandgaps that limit light absorption to the UV part of the spectrum, poor reaction kinetics at the interface photocatalyst surface and electrolyte. Coupling photocatalysts to nanoparticles and nanostructures made of plasmonic metals such as Au and Ag has been shown to enhance the overall photocatalytic performance of these materials. This enhancement is due to a combination of photonic effects due to enhanced light absorption in the visible and infrared parts of the spectrum and plasmonic effects such as direct electron transfer or a resonant energy transfer from plasmonic metal to the semiconductor photocatalyst. This poster presents our recent research on photocatalyst/plasmonic metal heterostructures and the mechanisms responsible for this enhancement.
Integrated CO2 Capture and Photocatalytic Conversion to Solar Fuels Using Multifunctional Materials
Authors: Liu Lianjun , Chen Jiatang , Li Ying
Published: February 2020

Photocatalytic conversion of CO2 with H2O to solar fuels is a promising technology to recycle CO2, a major greenhouse gas. However, the CO2-to-fuel conversion efficiency is typically low, mainly due to the fast recombination of photo-excited electron-hole pairs and limited absorption of solar spectrum by the photocatalyst. Some scientific challenges that have been overlooked in the literature are the photocatalyst’s ability to adsorb, activate and dissociate CO2, as well as the adsorption/desorption kinetics on the catalyst surface. To solve these problems, we have designed a new multifunctional material, porous microsphere MgO/TiO2 that performs as a hybrid adsorbent/photocatalyst, and we operated the CO2 photo-conversion temperature at around 150 oC. The higher reaction temperature enhanced intermediate/product desorption, and the addition of MgO improves CO2 adsorption at the MgO-TiO2 interface, particularly in the presence of water vapor. This multifunctional material demonstrated a significantly enhanced and more stable activity than pure TiO2 for CO2 photoreduction to CO. In situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) study was applied to identify surface intermediates and study the kinetics that is a critical factor governing the activity and stability of the photocatalyst. The effects of MgO morphology and dispersion on the TiO2 surface are also investigated.
Novel Photoelectrodes for the Flexible Mesoporous Sensitized Solar Cells
Authors: Ko Min Jae
Published: February 2020

Mesopoous dye-sensitized solar cell (DSC) has attracted much attention due to the high solar-to-electricity conversion efficiency up to 12% as well as low cost compared with p-n junction photovoltaic devices. Dramatic cost reduction can be accomplished by continuous roll-to-roll printing processes using a flexible plastic substrate. Therefore, lightweight and flexible DSC can be used as a ubiquitous power source for the future mobile electronics. For the realization of these purposes, some issues such as new fabrication method which can be applied to the plastic substrate should be required. In addition to that, durable mechanical stability of photoelectrode is strongly necessary. In this talk, several strategies to address these issues will be proposed.
Invited: High Efficiency V/V Redox Flow Battery Stack Utilizing Mixed Acid Electrolyte Chemistry

Published: February 2020

The demand for large-scale electrical energy storage (EES) devices has been growing for both improved efficiency and flexibility of the current grid infrastructure and to enable a higher penetration of stochastic renewable sources such like solar and wind onto the grid. Among the most promising technologies for the grid-scale EES are redox flow batteries (RFBs), which are capable of storing a large quantity of electricity (multi-MWs/MWhs) in a relatively simple and straightforward design. With support from the Department of Energy-Office of Electricity’s Energy Storage Program, PNNL developed a mixed-acid electrolyte (hydrochloric and sulfuric acid) for the all vanadium redox flow battery that offers significant improvements in thermal stability and solubility over the conventional, sulfate only system.

PNNL has incorporated the mixed acid electrolyte into kW scale systems in order to determine the optimal system efficiency at various flow, temperature, and current density conditions. A 15-cell stack utilizing Nafion® 115 was successfully operated at more 160 mA/cm2 over a 10 % - 90% SOC range with a stack energy efficiency of 74 %. At a flow rate of 6 lpm for both the catholyte and anolyte, the system obtained an overall efficiency (stack - pumping power) of 65%. With no active cooling the system reached a maximum temperature of 47°C. Replacing the 5 mil Nafion® 115 membrane with a 2 mil Nafion® 212, the energy efficiency increased to 79% while the operating temperature decreased to 43°C for the same 6 lpm flowrate. Further development was done on the catholyte and anolyte flow field to reduce the pressure drop through the stack. A new interdigitated flow field was designed and incorporated into the 15-cell stack. With the interdigitated flow field and the Nafion® 212 membrane, the stack efficiency remained at 79% but the system efficiency improved to 72% due to the lower pressure drop in the system. At 6 lpm flow rate, the interdigitated design resulted in ~ 3X decrease in the pressure drop across the cell (from an average of 6.5 psi to 2.5 psi for the interdigitated design). The operating temperature under these conditions was 40°C. Further testing of the interdigitated flow field and the Nafion® 212 membrane at 240mA/cm2 and the same electrolyte flow rate netted a stack energy efficiency of 71%, a system efficiency of 67%, and an operating temperature of 46°C.
Research and Development of Vanadium Flow Battery
Authors: Zhang Huamin
Published: February 2020

Renewable energies from sources like solar and wind become the central topics of our times with the concerns of energy shortage and environment protection. However, the random nature of these intermittent renewable sources (change with synoptic conditions, day and night alternation, etc.) makes it quite challenging for its use and dispatch through the grid. One effective solution is to connect the power station and the grid with electrical energy storage devices.

Vanadium redox flow battery (VFB) as one kind of energy storage techniques is rather suitable for this application due to its features like long life time, active thermal management as well as the independence of energy and power ratings. Dalian Institute of Chemical and Physics has devoted to VFB research for more than 10 years from materials to system integration, where VFB stacks with power rating from 5 W to 31 kW were successfully developed. To further accelerate its commercialization, a spin-off company (Rongke power Co.Ltd) was established in 2008, where different demonstrations of VFB in different application field were carried out. In 2012, a world largest 5MW/10MWh VFB system was successfully integrated and combined with a 50 MW wind farm.

In this presentation, the development of VFB in DICP will be introduced and the performance of VFB systems will be discussed in detail.

Advanced Hydrogen-Bromine Flow Battery for Energy Storage
Authors: Lin Guangyu , Chong Pau Ying , Nguyen Trung Van , Masud Jahangir , Wycisk Ryszard , Pintauro Peter N.
Published: February 2020

The hydrogen-bromine flow battery has been shown to be a promising candidate for energy storage due to its fast kinetics, fully reversible electrodes and low cost of chemicals. It features high electric-to-electric efficiency, high power density and simple system design. However, today's conventional hydrogen-bromine flow batteries use very expensive membrane materials (such as Nafion®) and platinum catalyst that can be poisoned and corroded when exposed to HBr and Br2. TVN Systems is developing an advanced H2-Br2 flow battery incorporating new catalysts that will be more durable than platinum in HBr/Br2 environment, new membranes with higher perm-selectivity at a fraction of the cost of conventional membranes and novel electrode/cell designs with superior cell performance. The performance, durability and cost advantages of this advanced H2-Br2flow batteries will be discussed.
