abstract: This review examines high performingenergy storage devices for high power applications including heavy electric vehicles, energy efficient cargo ships and locomotives, aerospace andstationary grid system.Such devices require systematic design and fabrication of composite nanostructured carbon based material and conductive polymers. Electrochemical capacitors based on nanostructured carbon can complement or replace batteries in electrical energy storage and harvesting applications whenever high power delivery or uptake is needed. Composite device of pseudo capacitive polymericmaterials and nanostructured carbon with the latest generation of nanostructured lithium electrodes has brought the energy density of electrochemical capacitors closer to that of batteries without compromising its specific power density, high capacitance and lifetime cycling stability.Energy storage devices' widespread applications in industrial, hybrid electric vehicles and commodity electronics could be facilitated through careful selection of electrolyte electrode system. Good understanding of charging mechanism is key to improving device's performance. Charging mechanism includes sequential ion desolations in pores smaller than the solvated ions through ion exchange or ion adsorption. This leads to higher capacitance for such storage devices. This has opened the door to designing advanced high energy density devices with fast charging and discharging times using a variety of electrolytes and nanostructured carbon polymer composite.

abstract: This review highlights the synthesis, structure modification, morphology, and properties of nano manganese dioxide (MnO2) Though MnO2 has been widely employed for electrode materials due to its superior electrochemica1 performance, abundant storage, low cost, and environmental friendly nature, the usage in bioapplications and dye mineralisation studies have started since few decades only. Currently, nano MnO2 plays an important role in solar cell devices and gas sensing as it can be easily tunable into desired polymerphic structure and morphology. Herein, the use of nano MnO2 as advanced material in energy, gas sensing, biological application and wastewater remediation are described. Based on the recent research, the available preparation procedures, surface modification and applications of nanostructured MnO2 are systematically presented. Also, structure stabilization and performance improvement of nano MnO2 by doping or composite formation with metals, carbon materials, and conductive polymers are summerised. According to the latest research progress, new trends and strategies of nano MnO2 towards specific applications besides energy storage application are focused in this review, as well as a brief overview of the challenges and future perspectives of MnO2, synthetic methodologies, and their state of the art applications in different fields are presented.

abstract: Over the past decades, flexible and wearable energy storage devices have received tremendous interest due to the development of smart electronic products, such as Apple Watch, Google Glass, and sport wristbands. Fiber shaped electrochemical energy storage devices (FEESDs) derived from fibrous electrodes are standing out as a result of the excellent flexibility and breathability compared with the planar counterparts. Textiles and fabrics can be simply achieved by spinning and weaving FEESDs, which perfectly match with an arbitrary uneven and mobile surface, revealing enormous potentialities in wearable electronics. Combining mechanical features with the electrically conductive properties and biocompatibility, conductive polymers (CPs) have emerged as a promising candidate for smart textile products including medical textiles, protective clothing, touch screen displays, and flexible fabric power supplies. In this context, this review summarizes the material design of CPs for fibrous electrodes and provides a critical discussion on their applications in flexible energy storage devices. Meanwhile, basic principles are briefly presented, including the conduction mechanism of conductive polymers, fibrous electrode design, and the evaluation of the electrochemical/mechanical performance for fibrous devices. Last, possibilities and challenges for the development of CP derived FEESDs are outlined as well.

abstract: Polyaniline (PANI) is considered one of the most preferred electrically conductive polymers (CPs) which is widely studied as an electrode material in designing next generation energy storage devices due to their chemical stability, fast redox reactions between the polymer and the electrolytes, high electrical conductivity, excellent electrochemical performance, and low cost. However, the inferior stability of PANI limits its application. In this work, the benefit of carbon dots (CDots) as light weight and spherical carbon based electrodes and fillers that allow the maintenance of the nanostructure of PANI while easing the ionic transport was studied together with the effect of manganese(ii) (Mn2+ doping on the overall capacitive properties of PANI. The integration of N doped spherical, nanosized carbon dots (N CDots) in the copolymerization of nanostructured PANI in the presence of varying concentrations of Mn2+ as a dopant synergistically improved the overall conductivity and specific surface area of the PANI based electrode and showed surface double layer ion exchange. Pseudocapacitance mechanisms were observed when the dopant concentration was kept at a molar percentage of Mn2+ to aniline of 1, which displayed exceptionally high specific capacitances of up to 595 F g 1. The asymmetric supercapacitor devices made with N CDot and nanostructured hybrid electrodes could reveal the great potential in the development of cheap yet efficient battery sized supercapacitor devices. In addition to extensive electrochemical performance, advanced EPR spectroscopy revealed detailed information regarding the defect structures of electrode materials in terms of understanding the conduction behavior of defect centers.

abstract: Nanostructured conductive polymers have been widely researched for various applications such as energy storage and conversion, chemical/biological sensors, and biomedical devices. Recently, novel synthetic methods which adopt doping molecules as cross linker have been developed to prepare conductive polymer gels (CPGs) with cross linked network and 3D hierarchically porous nanostructures. The CPGs, as well as their derived carbon frameworks, exhibit high electrical conductivity, large surface area, structural tunability, and hierarchical porosity for rapid mass/charge transport, which contribute to their high performance when applied for energy storage and conversion devices. This Perspective highlights the key features of CPGs and their derived carbon frameworks, discusses their possibilities in terms of rational synthesis and energy related applications, and proposes future directions for their technological development.

abstract: Three dimensional (3D) nanostructured conducting polymer hydrogels represent a group of high performance electrochemical energy storage materials. Here, we demonstrate a molecular self assembly approach toward controlled synthesis of nanostructured polypyrrole (PPy) conducting hydrogels, which was "cross linked" by a conjugated dopant molecule trypan blue (TB) to form a 3D network with controlled morphology. The protonated TB by ion bonding aligns the free sulfonic acid groups into a certain spatial structure. The sulfonic acid group and the PPy chain are arranged by a self sorting mechanism to form a PPy nanofiber structure by electrostatic interaction and hydrogen bonding. It is found that PPy hydrogels doped with varying dopant concentrations and changing dopant molecules exhibited controllable morphology and tunable electrochemical properties. In addition, the conjugated TB dopants promoted interchain charge transport, resulting in higher electrical conductivity (3.3 S/cm) and pseudocapacitance for the TB doped PPy, compared with PPy synthesized without TB. When used as supercapacitor electrodes, the TB doped PPy hydrogel reaches maximal specific capacitance of 649 F/g at the current density 1 A/g. The result shows that PPy nanostructured hydrogels can be tuned for potential applications in next generation energy storage materials.
