Ilika Ships 10Ah Goliath Battery Prototypes

 

Commencement of shipping marks latest on-schedule development milestone

 

Ilika (AIM: IKA), the UK pioneer in solid state battery technology, has begun
shipping its new 10Ah Goliath battery prototypes to customers across
multiple industries, including automotive companies. These new
prototypes offer five times more capacity than the 2Ah P1 prototypes
delivered to customers in July 2024.

 

The 10Ah cells feature a proprietary oxide coating which offers improved
safety, allowing electric vehicle manufacturers to design lighter and less
expensive 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 manufactured on Ilika's automated pilot line, completed in
October 2025. The automation has already shown significant benefits, with the
first batch achieving a 93% manufacturing success rate (yield), which is
well above the minimum required for moving to full production.

 

The Company has also created initial samples of larger 50Ah P2 cells for
testing, which will be available for shipping after feedback has been received
on the current 10Ah cells which is expected during 2026.

 

Graeme Purdy, CEO of Ilika, said: "We are excited that 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."

 

Head of Battery Development at a major UK automotive supplier serving global
car manufacturers 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."
