Solvay to supply lithium salt for Bolloré batteries
Contract based on common R&D programme
Solvay’s Aroma Performance Global Business Unit has agreed a multi-year contract to supply Batscap and BatHium Canada, which are both affiliates of the Bolloré Group affiliates, with specialty lithium salt grades (LiTFSI) for their Lithium-Metal-Polymer (LMP) batteries. The agreement is the result of a shared R&D programme between the firms, as was a previous strategic supply contract for speciality grades of Solvay's Solef PVD polymer.
The electrolytes will be made at the business unit’s speciality fluorinated derivatives plant at Salindres, France, and in China. According to Solvay, LiTFSI is the preferred option for the LMP batteries for use in the group’s fully electric vehicles like the Bluecar and the Autolib’, thanks to its combination of chemical and thermal stability with excellent electrochemical properties. It plans to increase its capacity further as demand from Batscap and BatHium grows.
The Aroma Performance business unit, which was part of Rhodia before the merger with Solvay, is said to be the world leader in diphenols and fluoro-aliphatic derivatives and in the production and sale of LiTFSI. It also produces food flavourings and intermediates for the perfumery, agro-food, electronics and pharmaceuticals industries.
