Moscow, Feb 24: Rosatom Chemistry JSC (AO “Rosatom Khimia”), a subsidiary of Rosatom’s Fuel division, has launched the pilot production of eight electrolyte grades. These products are used as components in the manufacturing of battery cells, which are subsequently assembled into batteries for a variety of applications. The company has developed its own manufacturing process and mastered the production of electrolytes for both non-rechargeable and rechargeable batteries, including lithium-ion and post-lithium systems such as sodium-ion and potassium-ion batteries. These electrolytes ensure consistent battery performance even at such low temperatures as -40°C, enhance the battery’s lifespan and improve the efficiency of the charge-discharge cycle. The know-how employed allows for achieving high transparency, stability, and a prolonged shelf life for the chemical composition.
The pilot production has been arranged at Rosatom Chemistry JSC research and development center in Moscow. This facility is capable of producing electrolytes for chemical power sources in full compliance with the specifications of the customers. Currently, the pilot facility produces 6 tons of electrolyte annually, but there are plans to increase production to 50 tons in the near future with strategic plans including the arrangement of a large-scale production with a capacity of up to 10,000 tons. The capacity increase is driven by the growing market demand in Russia and the production of lithium-ion batteries by Rosatom. In December 2025, Rosatom started pilot commercial operation of Russia’s first gigafactory for energy storage systems in the Kaliningrad Oblast, while a similar facility is currently under construction in New Moscow.
“Most lithium-ion battery manufacturers opt for procuring pre-made electrolytes rather than producing them in-house. Rosatom’s production of battery cell components is a further step towards strengthening the national technological independence in the strategic battery sector. Our research and development center has mastered the entire process, from designing the chemical composition of electrolytes to assembling test batteries to ensure the compliance with customer requirements. With our expertise, we are able to thoroughly inspect every component in a completed cell,” said Kristina Tikhomirova, Development Director at Rosatom Chemistry JSC.
The electrolyte manufactured by Rosatom Chemistry JSC has been qualified by a number of Russian battery producers and is currently undergoing trials at nine companies operating in various sectors. The electrolyte has already been supplied to Russian manufacturers of medical and specialized equipment, such as pacemakers, solar batteries, and spacecraft batteries, as well as to a prominent energy research and development center.
