Ilika, the UK pioneer in solid-state battery technology, has begun shipping its new 10Ah Goliath battery prototypes to customers across multiple industries, including automotive manufacturers. These prototypes deliver five times the capacity of the 2Ah P1 prototypes supplied in July 2024.
The 10Ah cells incorporate a proprietary oxide coating that enhances safety, enabling electric vehicle manufacturers to design lighter and more cost-effective battery packs. According to analysis by automotive experts
Balance Batteries, this technology could reduce battery pack weight by 20% and cut manufacturing costs by £2,500 per vehicle.
The prototypes were produced on Ilika’s automated pilot line, which was completed in October 2025. The automation has already demonstrated significant benefits, with the first batch achieving a 93% manufacturing success rate, well above the threshold required for scaling to full production. Ilika has also developed initial samples of larger 50Ah P2 cells for testing, which will be shipped after feedback on the current 10Ah cells is received during 2026.
Graeme Purdy, CEO of Ilika, said: “We are excited that our new automated pilot line is now producing high-quality, consistent battery prototypes for our partners to evaluate. This achievement is a significant milestone toward bringing our technology to market, further opening the window for licensing discussions with manufacturers.”
The head of battery development at a major UK automotive supplier said: “Here in the UK and more broadly in Europe, there is significant interest in developing technical solutions that are differentiated from the offerings available from established cell manufacturers. We look forward to evaluating these 10Ah prototypes from Ilika, which demonstrate the company’s sustained capability to improve and mature their product for commercial roll-out.”
The launch of the 10Ah Goliath prototypes marks a major step forward for Ilika as it moves closer to commercialisation and strengthens the UK’s position in next-generation battery technology.
