Quick Takeaways
- Ilika has delivered 10Ah solid-state Goliath battery prototypes, marking a major scale-up milestone for automotive EV applications.
- Pilot-line manufacturing validates readiness for scalable production while paving the way toward higher-capacity 50Ah cells.
On December 11, Ilika reached a key development milestone in Ilika solid-state battery technology by delivering its latest 10Ah Goliath battery prototypes to customers spanning several sectors, including leading automotive manufacturers. These cells mark a major scale-up step, offering five times the energy capacity of the earlier 2Ah P1 prototypes supplied in July 2024, while maintaining the core safety and performance advantages of solid-state design.
Ilika Solid-State Battery Technology Scales Up for EV Use
The new 10Ah Goliath cells integrate Ilika’s proprietary oxide-based coating, engineered to enhance thermal stability and overall safety. This design approach addresses one of the most critical challenges for electric vehicle platforms, enabling manufacturers to rethink battery pack architecture without compromising protection or durability.
For automotive OEMs, the implications are significant. By improving intrinsic cell safety, the Ilika solid-state battery platform supports simplified pack designs that can reduce structural reinforcement and auxiliary protection systems.
Key benefits highlighted by Ilika include:
These gains directly support automakers’ objectives to extend driving range, improve vehicle efficiency, and lower total EV production costs.
Manufacturing Readiness and Pilot-Line Validation
Production of the 10Ah Goliath prototypes was completed in October 2025 on Ilika’s automated pilot manufacturing line. This step demonstrates not only laboratory success but also progress toward scalable, repeatable production processes required for future commercial deployment.
Pilot-line manufacturing validates several critical factors:
Such validation is essential as solid-state battery technologies transition from development programs to industrial adoption.
Roadmap Toward Higher-Capacity Cells
Alongside the 10Ah program, Ilika has already produced initial samples of its next-generation 50Ah P2 cells. These larger-format cells are intended to meet the capacity demands of full-scale electric vehicle battery packs and other high-energy applications.
Shipment of the 50Ah P2 cells is planned after customer feedback on the current 10Ah Goliath cells is evaluated. Ilika expects this feedback cycle to extend through 2026, guiding further optimization in performance, manufacturability, and cost.
As development continues, the Ilika solid-state battery roadmap reflects a structured progression from prototype validation to higher-capacity formats aligned with automotive production requirements, reinforcing the company’s position in the evolving solid-state battery landscape.
