UK battery developer Ilika has shipped its first batch of prototype solid state battery pouch cells for testing by a tier 1 automotive company.
Ilika started in -house testing of its P1 Goliath prototype batteries in May in a customer-sponsored programme and the first batch have now been sent to a customer for external validation.
The cells, with an NMC cathode, silicon anode and solid electrolyte in four stacks, have an energy density of 250 Wh/kg and a capacity of 0.715 Ah, comparable to lithium ion cells.

This follows the announcement last year that Ilika had achieved its D4 development point – a design-freeze milestone in the Goliath roadmap upon which Ilika’s first prototype for customer release, P1, is based.
The P1 prototype is an intermediate milestone on Ilika’s roadmap to its minimum viable product (MVP) in 2025. Ilika’s Goliath MVP, or P2 prototypes, will underpin licensing opportunities.

“Following up on the encouraging results from our P1 test programme, we are delighted to be engaging with a portfolio of interested OEMs and Tier 1 companies on commercially sponsored evaluation trials,” said Graeme Purdy, CEO of Ilika.
