UK-headquartered solid-state battery developer Ilika has shipped its first batch of prototype Goliath batteries for customer testing by a Tier 1 automotive company.
The company performed in-house testing of the P1 Goliath prototype batteries beginning in May in a customer-sponsored program.
Goliath batteries employ a ceramic electrolyte rather than a liquid one, and are made with a silicon anode and an oxide solid electrolyte. According to Ilika, the batteries’ higher cell-to-pack ratio can lead to lighter vehicles, faster charging and longer range.
Ilika announced last year that it had achieved its D4 development point in the Goliath road map, which its PI prototype for customer release is based on. Reaching the D4 point means that the Goliath solid-state pouch cell can now achieve an effective specific energy of 250 Wh/kg and a capacity of 0.715 Ah, which the company says matches the representative energy density of incumbent lithium-ion pouch cells.
The P1 prototype is a solid-state pouch cell with a nickel-manganese-cobalt (NMC) cathode and a silicon anode. It is an intermediate stage in the development of the company’s P2 prototypes (its minimum viable product), which will be made available for OEM licensing in 2025.
