# History of the lithium-ion battery

This is a history of the lithium-ion battery.

## Before lithium-ion: 1960-1975

* 1960s: Much of the basic research that led to the development of the intercalation compounds that form the core of lithium-ion batteries was carried out in the 1960s by Robert Huggins and Carl Wagner, who studied the movement of ions in solids. In a 1967 report by the US military, plastic polymers were already used as binders for electrodes and graphite as a constituent for both cathodes and anodes, mostly for cathodes.
* 1970s: Reversible intercalation of lithium ions into graphite as anodes and intercalation of lithium ions into cathodic oxide as cathodes was discovered during 1974–76 by Jürgen Otto Besenhard at TU Munich. Besenhard proposed its application in lithium cells. What was missing in Besenhard's batteries is a solvent showing no co-intercalation into graphite, electrolyte decomposition and corrosion of current collectors. Thus, his batteries had very short cycle lives.
* 1970s: Reversible intercalation of lithium ions into layered cathode materials. British chemist M. Stanley Whittingham, then a researcher at ExxonMobil, first reported a charge-discharge cycling with a lithium metal battery (a precursor to modern lithium-ion batteries) in the 1970s. Drawing on previous research from his time at Stanford University, he used a layered titanium(IV) sulfide as cathode and lithium metal as anode. However, this setup proved impractical. Titanium disulfide was expensive (~$1,000 per kilogram in the 1970s) and difficult to work with, since it has to be synthesized under completely oxygen- and moisture-free conditions. When exposed to air, it reacts to form hydrogen sulfide compounds, which have an unpleasant odour and are toxic to humans and most animals. For this, and other reasons, Exxon discontinued development of Whittingham's lithium-titanium disulfide battery.
Batteries with metallic lithium electrodes presented safety issues, most importantly the formation of lithium dendrites, that internally short-circuit the battery resulting in explosions. Also, dendrites often lose electronic contact with current collectors leading to a loss of cyclable Li+ charge. Consequently, research moved to develop batteries in which, instead of metallic lithium, only lithium compounds are present, being capable of accepting and releasing lithium ions.
* 1973: Adam Heller proposed the lithium thionyl chloride battery, still used in implanted medical devices and in defense systems where a greater than 20-year shelf life, high energy density, and/or tolerance for extreme operating temperatures are required. However, this battery employs unsafe lithium metal and was not rechargeable.

## Precommercial development: 1974-1990

* 1974: Besenhard was the first to show reversibility of Li-ion intercalation into graphite anodes, using organic solvents, including carbonate solvents.
* 1976: Stanley Whittingham and his colleagues at Exxon demonstrated what can be considered the first rechargeable "lithium-ion battery", although not a single component in this design was used in commercial lithium-ion batteries later. Whittingham's cell was assembled in a charged state using lithium aluminum alloy as the negode, LiBPh4 (lithium tetraphenylborate) in dioxolane as the electrolyte and TiS2 as the posode. The battery useful cycle life was no more than 50 cycles. This design was based on Whittigham's earlier Li-metal batteries.
* 1977: Samar Basu et al. demonstrated irreversible intercalation of lithium in graphite at the University of Pennsylvania. This led to the development of a workable lithium intercalated graphite electrode at Bell Labs in 1984 (LiC $_6$) to provide an alternative to the lithium metal electrode battery. However it was only a molten salt cell battery rather than a lithium-ion battery.
* 1978: Michel Armand introduced the term and a concept of a rocking-chair battery, where the same type of ion is de/intercalated into both positive and negative electrode during dis/charge. In the rocking-chair design solution-phase species do not appear in the reaction stoichiometry, which allows for minizing the amount of solvent in the battery, reduces the battery weight and cost.
* 1979: Working in separate groups, Ned A. Godshall et al., and, shortly thereafter, John B. Goodenough (Oxford University) and Koichi Mizushima (Tokyo University), demonstrated limited discharge-charge cycling of a 4 V cell made with lithium cobalt dioxide (LiCoO $_2$) as the positive electrode and lithium metal as the negative electrode. This innovation provided the positive electrode material, which eventually became a component in the first commercial rechargeable lithium-ion battery. LiCoO $_2$ is a stable positive electrode material which acts as a donor of lithium ions, which means that it can be used with a negative electrode material other than lithium metal. By enabling the use of stable and easy-to-handle negative electrode materials, LiCoO $_2$ enabled novel rechargeable battery systems. Godshall et al. further identified the similar value of ternary compound lithium-transition metal-oxides such as the spinel LiMn$_2$O$_4$, Li$_2$MnO$_3$, LiMnO$_2$, LiFeO$_2$, LiFe$_5$O$_8$, and LiFe$_5$O$_4$ (and later lithium-copper-oxide and lithium-nickel-oxide cathode materials in 1985) Godshall et al. patent U.S. patent 4,340,652 for the use of LiCoO$_2$ as cathodes in lithium batteries was based on Godshall's Stanford University Ph.D. dissertation and 1979 publications.
* 1980: M.Lazzari and Bruno Scrosati at the University of Rome validated the concept of rocking-chair battery using lithium tungsten dioxide as the anode, titanium disulfide as the cathode and lithium perchlorate in propylene carbonate as the electrolyte.
* 1980's: The negative electrode has its origins in PAS (polyacenic / polyacetylene semiconductive material) discovered by Tokio Yamabe and later by Shizukuni Yata in the early 1980s. This development was inspired by an earlier discovery of conductive polymers by Professor Hideki Shirakawa and his group, and it could also be seen as having started from the polyacetylene lithium-ion battery developed by Alan MacDiarmid and Alan J. Heeger et al.
* 1983: Rachid Yazami demonstrated the reversible electrochemical intercalation of lithium in graphite at room temperature using polyethylene oxide solvent. The organic battery solvents, known at the time, decompose during charging with a graphite negative electrode. For this reason, Yazami used a solid electrolyte to demonstrate that lithium could be reversibly intercalated into graphite via an electrochemical mechanism at room temperature.
* 1983: Michael M. Thackeray, Peter Bruce, William David, and John B. Goodenough developed manganese spinel, Mn$_2$O$_4$, as a charged cathode material for lithium-ion batteries. It has two flat plateaus on discharge, with lithium one at 4 V, stoichiometry LiMn$_2$O$_4$, and one at 3 V with a final stoichiometry of Li$_2$Mn$_2$O$_4$.
* 1985: Akira Yoshino demonstrated a rechargeable Li-ion battery using carbonaceous material (acetylene black), into which lithium ions could be inserted, as the negative electrode (anode) and lithium cobalt oxide (LiCoO $_2$) as the positive electrode (cathode). This dramatically improved safety LiCoO $_2$ and prepared Sony for commercial launch of a rechargeable lithium-ion battery 5 years later. Yoshino's design in 1985 was different from the final (1990) design in using 0.6 mol of LiClO$_4$ (rather than LiPF$_6$) in propylene carbonate (without ethylene or linear carbonate used currently to passivate the graphite negode) and in using polyacrylonitrile rather than polyvinylidene difluoride as the binder.
* 1986 : Around the same time as Akira Yoshino, Auborn and Barberio at Bell Laboratory independently demonstrated another true rocking-chair battery assembled in the fully discharged state. Their 1.8 V lithium-ion battery comprised LiCoO2 as the posode, 1M LiPF6 in propylene carbonate as the electrolyte and MoO2 as the negode.
* 1986 : Asahi researchers, led by Akira Yoshino, demonstrated rechargeable battery with lithium tetrafluoroborate (LiBF4) dissolved in a mixture of PC, gamma-butyrolactone (γBL) and ethylene carbonate (EC), as the electrolyte. The fluorinated anion turned out to be effective in passivating the Al current collector and compatible with the solvents, while ethylene carbonate (which is solid at room temperature and is mixed with other solvents to make a liquid) provided th necessary solid electrolyte interphase on the anode, thus publicly disclosing the final piece of the puzzle leading to the modern lithium-ion battery. This design was practically identical (except for LiBF4 being replaced with LiPF6, which is less reactive with the solvent(s)) to the one used in commercial lithium-ion batteries today.
* 1987-1989: Arumugam Manthiram and John B. Goodenough discovered the polyanion class of cathodes. They showed that positive electrodes containing polyanions, e.g., sulfates, produce higher voltages than oxides due to the inductive effect of the polyanion. This polyanion class contains materials such as lithium iron phosphate.
* 1989:The recall of Moli Energy cells, comprising lithium metal, abruptly changed researchers’ perception in favor of heavier but safer dual-intercalation (i.e. lithium-ion rather than lithium-metal) batteries.
* 1989-10-11: Jeff Dahn and two colleagues at Moli Energy in Burnaby (Canada) submit a journal article, proving a reversible intercalation of lithium ions into graphite in the presence of ethylene carbonate solvent (in 50:50 mixture with propylene carbonate and with 1M LiAsF6 salt), and demonstrating the formation of solid electrolyte intephase on the first charge, followed by a reversible battery cycling. This is essentially the composition, which will be used in commercial Li-ion batteries since 1992, except for LiAsF6 having been replaced with cheaper and less toxic LiPF6.
* 1990: Rachid Yazami at the French National Centre for Scientific Research in Grenoble, France starts collaborating with Sony on developing graphite anode and liquid electrolyte for lithium-ion batteries, eventually discovering the magic ethylene carbonate solvent, which resulted in almost doubling (to 155 Wh/kg) the specific energy of cells with soft carbon anodes.
* 1990-12-10: Sanyo Electric of Japan files a patent application, that describes a rechargeable (ca. 250 cycles) lithium metal battery with a mixed ethylene carbonate + dimethyl carbonate solvent and LiPF6 as the electrolyte.
* 1990: The English term "lithium-ion battery", which was invented as a marketing tool to distinguish the new technology from ill-fated lithium metal batteries appeared for the first time in a publication. It was used by Sony employees.
In 2017 (2 years before the 2019 Nobel Prize in Chemistry was awarded) George Blomgren offered some speculations on why Akira Yoshino's group produced a commercially viable lithium-ion battery before Jeff Dahn's group:
* The Dahn group tested the carbonaceous positive electrode against lithium instead of a metal oxide. Therefore, they did not observe the severe corrosion of an aluminum positive current collector with the LiAsF6 electrolyte, but Yoshino et al. used ... LiPF6, which was commonly used for primary lithium metal batteries in Japan.
* Yoshino et al. also studied various binders including the ultimate winner- polyvinylidene fluoride, while Dahn's group used only ethylene propylene diene monomer (EPDM), which turned out to be not durable enough for commercial LIBs.

## Commercialization in portable applications: 1991-2007

The performance and capacity of lithium-ion batteries increased as development progressed.
* 1991: Sony and Asahi Kasei started commercial sale of the first rechargeable lithium-ion battery. The Japanese team that successfully commercialized the technology was led by Yoshio Nishi. 1991 ushered the Second Period (commercialization) in the history of lithium-ion batteries, which is reflected as inflection points in the plots "The log number of publications about electrochemical powersources by year" and "The number of non-patent publications about lithium-ion batteries" shown on this page. The battery employed soft carbon (rather than graphite) anode and LiCoO2 cathode. Sony's success with the development of lithium-ion battery manufacturing benefited from the company's prior experience with manufacturing monodisperse (20 μm) metal oxide microparticles and with coating processes for magnetic tapes.
* 1994: iconectiv First commercialization of Li polymer by Bellcore.
* 1994: The first aqueous Li-ion “rocking chair” chemistry was demonstrated by Dahn et al. It had a VO2 anode and LiMn2O4 cathode in a 5 M LiNO3 electrolyte with 1 mM LiOH.
* 1996: Goodenough, Akshaya Padhi and coworkers proposed lithium iron phosphate (LiFePO $_4$) and other phospho-olivines (lithium metal phosphates with the same structure as mineral olivine) as positive electrode materials.
* 1996: Sony and Nissan announced a partnership to develop a lithium-ion battery powered car FEV II with a 124 mile driving range.
* 1998: C. S. Johnson, J. T. Vaughey, M. M. Thackeray, T. E. Bofinger, and S. A. Hackney report the discovery of the high capacity high voltage lithium-rich NMC cathode materials.
* 2001: Arumugam Manthiram and co-workers discovered that the capacity limitations of layered oxide cathodes is a result of chemical instability that can be understood based on the relative positions of the metal 3d band relative to the top of the oxygen 2p band. This discovery has had significant implications for the practically accessible compositional space of lithium-ion battery layered oxide cathodes, as well as their stability from a safety perspective.
* 2001: Christopher Johnson, Michael Thackeray, Khalil Amine, and Jaekook Kim file a patent for lithium nickel manganese cobalt oxide (NMC) lithium rich cathodes based on a domain structure.
* 2001: Zhonghua Lu and Jeff Dahn file a patent for the NMC class of positive electrode materials, which offers safety and energy density improvements over the widely used lithium cobalt oxide.
* 2002: Yet-Ming Chiang and his group at MIT showed a substantial improvement in the performance of lithium batteries by boosting the LiFePO4 material's conductivity by doping it with aluminium, niobium and zirconium. The exact mechanism causing the increase became the subject of widespread debate.
* 2004: Yet-Ming Chiang again increased performance by utilizing lithium iron phosphate particles of less than 100 nanometers in diameter. This decreased particle density almost one hundredfold, increased the positive electrode's surface area and improved capacity and performance. Commercialization led to a rapid growth in the market for higher capacity lithium-ion batteries, as well as a patent infringement battle between Chiang and John Goodenough.
* 2004: The number of non-patent publications about lithium-ion batteries from PR China surpassed that from the USA. Japan was the third leading country till 2011, when it was surpassed by South Korea.
* 2005: Y Song, PY Zavalij, and M. Stanley Whittingham report a new two-electron vanadium phosphate cathode material with high energy density

## Commercialization in automotive applications: 2008-today

* 2008: The launch of Tesla Roadster- the first highway legal, serial production, all-electric car to use lithium-ion battery cells, and the first production all-electric car to travel more than 244 miles (393 km) per charge- ushered a new era in the history of Li-ion batteries, which is signified as inflection points in the plots "The log number of publications about electrochemical powersources by year" and "The number of non-patent publications about lithium-ion batteries" shown on this page.
* 2011: Lithium nickel manganese cobalt oxide (NMC) cathodes, developed at Argonne National Laboratory, are manufactured commercially by BASF in Ohio.
* 2011: Lithium-ion batteries accounted for 66% of all portable secondary (i.e., rechargeable) battery sales in Japan.

## Market

Industry produced about 660 million cylindrical lithium-ion cells in 2012; the 18650 size is by far the most popular for cylindrical cells. If Tesla were to have met its goal of shipping 40,000 Model S electric cars in 2014 and if the 85 kWh battery, which uses 7,104 of these cells, had proved as popular overseas as it was in the United States, a 2014 study projected that the Model S alone would use almost 40 percent of estimated global cylindrical battery production during 2014. As of 2013, production was gradually shifting to higher-capacity 3,000+ mAh cells. Annual flat polymer cell demand was expected to exceed 700 million in 2013.
Prices of lithium-ion batteries have fallen over time. Overall, between 1991 and 2018, prices for all types of lithium-ion cells (in dollars per kWh) fell approximately 97%. Over the same time period, energy density more than tripled. Efforts to increase energy density contributed significantly to cost reduction.
In 2015, cost estimates ranged from $300–500/kWh. In 2016 GM revealed they would be paying US$145/kWh for the batteries in the Chevy Bolt EV. In 2017, the average residential energy storage systems installation cost was expected to drop from $1600 /kWh in 2015 to $250 /kWh by 2040 and to see the price with 70% reduction by 2030. In 2019, some electric vehicle battery pack costs were estimated at $150–200, and VW noted it was paying US$100/kWh for its next generation of electric vehicles.
Batteries are used for grid energy storage and ancillary services. For a Li-ion storage coupled with photovoltaics and an anaerobic digestion biogas power plant, Li-ion will generate a higher profit if it is cycled more frequently (hence a higher lifetime electricity output) although the lifetime is reduced due to degradation.
Several types of lithium nickel cobalt manganese oxide (NCM) and lithium nickel cobalt aluminium oxide (NCA) cathode powders with a layered structure are commercially available. Their chemical compositions are specified by the molar ratio of component metals. NCM 111 (or NCM 333) have equimolar parts of nickel, cobalt and manganese. Notably, in NCM cathodes, manganese is not electroactive and remains in the oxidation state +4 during battery's charge-discharge cycling. Cobalt is cycled between the oxidation states +3 and +4, and nickel - between +2 and +4. Due to the higher price of cobalt and due to the higher number of cyclable electrons per nickel atom, high-nickel (also known as "nickel-rich") materials (with Ni atomic percentage > 50%) gain considerable attention from both battery researchers and battery manufacturers. However, high-Ni cathodes are prone to O2 evolution and Li+/Ni4+ cation mixing upon overcharging.
As of 2019, NMC 532 and NMC 622 were the preferred low-cobalt types for electric vehicles, with NMC 811 and even lower cobalt ratios seeing increasing use, mitigating cobalt dependency. However, cobalt for electric vehicles increased 81% from the first half of 2018 to 7,200 tonnes in the first half of 2019, for a battery capacity of 46.3 GWh.
In 2010, global lithium-ion battery production capacity was 20 gigawatt-hours. By 2016, it was 28 GWh, with 16.4 GWh in China. Production in 2021 is estimated by various sources to be between 200 and 600 GWh, and predictions for 2023 range from 400 to 1,100 GWh.
An antitrust-violating price-fixing cartel among nine corporate families, including LG Chem, GS Yuasa, Hitachi Maxell, NEC, Panasonic/Sanyo, Samsung, Sony, and Toshiba was found to be rigging battery prices and restricting output between 2000 and 2011.
