Ilika, a developer of solid-state battery technology, has successfully shipped its first batch of prototype Goliath batteries to a tier 1 automotive company for testing. This milestone follows Ilika’s announcement in May 2024 that it had begun in-house testing of its P1 Goliath prototype batteries. The P1 prototypes were part of a customer-sponsored program, and this initial batch has now been sent out for external validation.
In the previous year, Ilika reached a significant milestone known as the D4 development point. This design-freeze milestone on the Goliath roadmap was crucial for the development of the P1 prototypes. The D4 development point was achieved by meeting key data sets, including matching the energy density of traditional lithium-ion batteries. Specifically, the Goliath solid-state pouch cell attained an energy density of 250 Wh/kg and a capacity of 0.715 Ah, equalling the representative energy density of current lithium-ion pouch cells.
These achievements enabled the creation of P1 samples, which consist of at least four-layer stacks, and these samples have now been provided to OEMs for testing. The P1 prototype is a solid-state pouch cell that features an NMC cathode and a silicon anode. This prototype represents an intermediate step on Ilika’s roadmap towards its minimum viable product (MVP), targeted for 2025.
Ilika’s Goliath MVP, or P2 prototypes, will serve as the foundation for future licensing opportunities, paving the way for further advancements in solid-state battery technology.
