Ilika has reached its D6 milestone by testing 10 Ah cells in its Goliath solid-state batteries for electric vehicles.

The modelling of a Goliath-based battery pack for EVs is under way by UK company Balance Batteries. Early results show the weight of the battery pack can be reduced by up to 100 kg on the basis of Goliath’s benefits, compared to a current SUV lithium-ion model of the same energy.

Ilika is now progressing with development towards a D7 design freeze, which it expects to achieve in Q1 2025. This will form the basis of a release of 10 Ah prototype cells to customers, called the P1.5 prototypes; an upgrade of the 2 Ah P1 prototypes released in July 2024.

The timing of the P1.5 release will be driven by completion of testing of a batch of batteries based on the D7 design by Q2 2025.

The 2025 development roadmap will then extend to a D8 design freeze, which is also expected in Q1 2025, and then to the crucial Minimum Viable Product stage, targeted for the end of 2025.

Ilika CEO Graeme Purdy said: “Meeting our D6 development milestone on schedule is a key marker to ensure we are progressing towards an MVP that meets or exceeds customer expectations.

“Safety is a key differentiator for solid-state technology in the EV market, but also differentiates Ilika versus its solid-state peers as it seeks to lead the sector on this point… Ilika’s technology is a step closer to market readiness and commerciality.”
