Global automaker Stellantis has invested $US15M in Element 25 (ASX:E25), a manganese and battery technology company.

Element 25 said it will use this investment to further its development of a battery-grade high purity manganese sulphate monohydrate (HPMSM) facility in the USA.

As part of their agreement, Stellantis will receive 45kt of HPMSM from the new facility over a period of five years and the investment is structured to be repaid out of the HPMSM supplied to Stellantis.

Element 25 also has another arrangement with General Motors’ USA Ultium Battery Plants to supply HPMSM, which includes an $US85M loan facility, taking E25's current project commitments to $US115M.
