Hampshire-based Ilika has begun shipping new solid-state battery prototypes to clients across several industries, including automotive manufacturers. The 10Ah Goliath cells offer five times the capacity of the 2Ah P1 prototypes delivered in July 2024.
The new cells feature a proprietary oxide coating, which enhances safety and allows vehicle makers to design lighter, less expensive battery packs. Analysis by automotive consultancy Balance Batteries suggests the technology could reduce battery pack weight by 20 per cent and cut manufacturing costs by around £2,500 per vehicle.
The prototypes were produced on Ilika’s automated pilot line, completed in October 2025, with the first batch achieving a 93 per cent manufacturing success rate, surpassing the threshold required for full production.
Initial samples of larger 50Ah P2 cells have also been created for testing. These will be shipped after feedback is received on the current 10Ah prototypes, expected in 2026.
Graeme Purdy, chief executive 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 added: “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.”
