PGMs: Independent tests advance platinum and palladium battery technology
[SMM PGM Flash] Platinum Group Metals said on 1 October that independent testing by the Battery Innovation Center had validated its Lion Battery subsidiary’s platinum- and palladium-based electrodes in prototype lithium-sulphur cells. Compared with cells without the catalysts, the prototypes showed better capacity and rate capability, with palladium-rich formulations performing best overall. Platinum Group and Valterra Platinum, which own Lion 52% and 48% respectively, have approved funding for the next phase.
The result offers a possible new use for PGMs beyond vehicle exhaust catalysts, but remains a prototype milestone. Lion plans to make and test pouch cells, refine the catalysts and assess applications including drones. Commercial performance and demand for significant PGM volumes have yet to be established. The work is relevant to Southern African suppliers: Valterra produces PGMs in South Africa and Zimbabwe, while Platinum Group is developing South Africa’s Waterberg project.
