Ilika PLC (AIM:IKA, OTCQX:ILIKF), the solid-state battery specialist, has started sending out its latest Goliath prototypes, a step the company says puts it firmly on schedule as it works towards commercial production.
The new 10Ah cells, which are heading to customers in several industries, including carmakers, carry five times the capacity of the 2Ah versions Ilika released in July 2024. In simple terms, the higher the amp-hour rating, the more energy a battery can store and the longer it can power a device or vehicle.
These prototypes were built on Ilika’s automated pilot line, completed in October 2025. Automation is crucial for any company trying to prove it can make batteries at scale rather than in the lab, and Ilika said its first run achieved a 93% yield — well above the minimum success rate needed before moving towards full production.
The group has also produced early samples of larger 50Ah P2 cells, but those will not be shipped until customers have provided feedback on the current generation, expected in 2026.
Graeme Purdy, Ilika’s chief executive, 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.”
A head of battery development UK automotive supplier serving global car makers 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.”
A key selling point is a proprietary oxide coating designed to improve safety. Solid-state batteries already replace the flammable liquid found in many conventional lithium-ion batteries, but Ilika says its coating could go further by allowing manufacturers to build lighter and cheaper battery packs.
Analysis from Balance Batteries, a consultancy working with the automotive sector, suggests pack weight could fall by 20% while cutting roughly £2,500 from the cost of each electric vehicle.
