The main foreign producers of lithium-ion accumulators are A123 Systems, Altair Nanotechnologies, Samsung SDI, Ener1 Battery Company, Dow Kokam, Saft Batteries, BYD, and Valence Technology.
A123 Systems produces cells, accumulator modules and ready-made energy storage units based on them for electric transport, the power industry and other consumers. According to company forecasts, its production capacities at the end of 2011 should total 660 MW*h/year. Lithium-ferrum-phosphate accumulators A123 are based on genuine Nanophosphate technology. The company produces accumulator cells, both in cylindrical and prismatic bodies.
Altair Nanotechnologies specializes in production of in-house anode material from lithium titanate (LTO), as well as accumulator modules and energy storage units for the power industry (major market), transport and uninterruptible power supply sources. Two foreign producers also produce accumulator cells for Altairnano. These are Korean Kokam è Eig Ltd.
Samsung SDI is also a noteworthy producer: in 2010, the company’s capacities totaled 960 mln. lithium-ion cells per year (mainly, for consumer electronics). Samsung SDI also supplies energy storage units for power industry. The company’s offers in this sphere are based on in-house large-sized lithium-ferrum-phosphate cells with a capacity of 50 À*h and range from small storage units for distribution networks (Community Energy Storage – CES) to large energy storage units, capable of providing system services (Energy Storage System).
Ener1 Battery Company produces lithium-ion accumulators and systems based on them for transport, the power industry and retail consumers. Plants are located in the U.S., Indiana and Korea. The forecast for production capacities for 2011 all over Ener1 is 253 MW*h.
Dow Kokam is a joint American-South Korean venture that produces lithium polymeric cells, accumulator modules and systems based on them for transport, industry, defense complex and uninterruptible power supply sources. The company has considerable production capacities: 150 MW*h cells a year in South Korea, 33 MW*h in the USA (Missouri) and assembly of 150 000 storage units a year (105 MW*h) in France. In 2012, it is also planned to start production at a large plant designed for 1.2 GW*h in the USA (Michigan).
Saft Batteries developed, on the basis of in-house lithium-ion accumulators, Intensium Max containerized storage units which can be used in power industry for support of work of renewable power sources. Energy storage units are based on the VL41M accumulator cylindrical cell with a cathode based on nickel oxide. Several cells of this kind form an accumulator module which is the basic element of the energy storage unit.
BYD (China), producing electric vehicles, solar batteries, invertors and lithium-ion accumulators, extended its product line into the sphere of energy storage units for the power industry. Such systems are based on Fe accumulator large-format lithium-ferrum-phosphate cells.
In Russia there is no production of analogues.
Several Russian plants produce lithium-ion accumulators of much lower capacity that are considerably inferior to Liotech accumulators:
Scientific Production Association SSK, Rigel JSC, NIIHIT-2, NIAI Istochnik OJSC, Energy OJSC.
Liotech lithium-ion accumulators are much lighter than other similar products (lead-zinc, nickel-metal-hybrid and other types of accumulators). The features of accumulators offered for production considerably exceed accumulators produced at present in Russia.
Scientific Production Association SSK, together with the Indian corporation of energy efficient technologies (INPSC), developed technology of producing of lithium-ion modules with a capacity up to 1000 À*h and voltage up to 300 V. Galvanic elements with a capacity 10-20 À*h serve as the basis for completing and cross-plugging of such battery assembles.
Rigel JSC produces lithium-ion accumulator modules with a capacity up to 260 À*h by means of integrating rechargeable batteries with a capacity of 1.5–15 À*h. Technical indicators are lower than those of their competitors (see table below).
