Lithium-ion batteries rely on critical minerals with geographically concentrated supply chains, creating potential vulnerabilities in cost, availability, and national security. Existing battery technologies may also pose safety risks due to flammability.

Group1 develops and commercializes potassium-ion (K-ion) batteries as a safer and more sustainable alternative to lithium-ion. Their K-ion technology utilizes abundant, domestically sourced materials, reducing reliance on constrained global supply chains. The batteries are designed to be non-flammable, enhancing safety for energy storage applications. Group1's K-ion batteries are engineered for seamless integration into existing lithium-ion manufacturing infrastructure, facilitating easier adoption and scalability.
