Highlights

  • Ilika begins shipping 10Ah Goliath prototypes, offering five times the capacity of 2Ah models.
  • Oxide coating in new cells may reduce EV battery pack weight by 20% and cut costs.
  • Automated pilot line achieves 93% manufacturing yield, supporting progress toward full production.

Ilika plc (LSE:IKA), a UK developer of solid-state battery technology, has started shipping its 10Ah Goliath battery prototypes to customers across different sectors, including automotive manufacturers. These cells provide a fivefold increase in capacity compared to the 2Ah P1 prototypes delivered in July 2024.

Safety and Cost Benefits with Oxide Coating
The 10Ah cells use a proprietary oxide coating designed to enhance safety. According to automotive analysis by Balance Batteries, the technology could reduce battery pack weight by 20% and lower manufacturing costs by GBP 2,500 per vehicle. This allows manufacturers to potentially design lighter and less expensive EV battery packs.

Automated Production Shows High Yield
The prototypes were produced on Ilika’s automated pilot line, completed in October 2025. The initial batch reached a 93% manufacturing success rate, exceeding the minimum requirement to progress toward full production.

Plans for Larger Cells
Ilika has also prepared initial samples of 50Ah P2 cells for testing. These larger cells will be made available for shipping after feedback on the 10Ah prototypes, expected during 2026.

Industry Perspective
A senior representative from a major UK automotive supplier highlighted the interest in developing differentiated technical solutions and expressed anticipation for evaluating the 10Ah prototypes.

Share Price Snapshot
IKA was trading 2.35% higher at GBX 43.50 per share as of 11 December 2025.
