Ilika has supplied its 10 Ah Goliath battery cells to About:Energy for independent testing, marking a further step towards commercialisation.
The UK-developed pouch cells have a stated energy density of 300 Wh/kg. Ilika’s Gen1 model is the first quasi-solid-state cell to be tested by About:Energy and will be assessed for its suitability across a range of applications.
The results will be added to About:Energy’s Voltt battery database. This should give Ilika and potential customers a clearer view of how the Goliath technology compares with application requirements and where it may offer the strongest commercial fit.
Automotive stakeholders are already evaluating the 10 Ah prototypes. Ilika has also reported interest from the defence sector, where battery safety and secure domestic supply can be important purchasing factors.
The company is also working with Brompton on possible e-bike applications. This gives the technology exposure to a market where weight, energy density, safety and charging performance are central to product design.
Ilika has developed two versions of the Goliath cell. Gen1 uses the company’s proprietary quasi-solid electrolyte, while Gen1L uses a liquid electrolyte.
Both variants use a high-silicon-content anode and a high-nickel nickel manganese cobalt cathode. Gen1 has a stated continuous discharge rate of 3C, while Gen1L has a stated rate of 6C.
The two-cell approach allows Ilika to target different operating requirements. Gen1 is positioned around the potential safety and performance benefits of a quasi-solid electrolyte. Gen1L offers a higher continuous discharge rate and may suit applications that require greater power output.
