Ilika, a pioneer in solid state battery technology, announces that it has shipped its first batch of prototype Goliath batteries for customer testing by a tier 1 automotive company.

In May 2024, Ilika announced it had commenced in-house testing of its P1 Goliath prototype batteries, in a customer-sponsored programme and the first batch have now been sent to a customer for external validation.

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 D4 development point was reached when key data sets were met. This included lithium-ion energy density parity, meaning the Goliath solid state pouch cell is now able to match the representative energy density of incumbent lithium-ion pouch cells, achieving an effective energy density of 250 Wh/kg and a capacity of 0.715 Ah.

This in turn enabled the P1 samples, comprising at least 4 layer stacks, to be created and then offered to OEMs for testing. The P1 prototype is a solid state pouch cell with an NMC cathode and a silicon anode and 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.

Graeme Purdy, Ilika CEO, stated: “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.”
