Trusted by industry leaders

Group14 works alongside global battery innovators and OEMs to bring silicon batteries out of the laboratory and onto the market. Industry leaders such as Molicel, ATL, Archer, and others have built products with SCC55®.

Applications

Charge in minutes. Drive for hours.

Electric vehicles need batteries that deliver longer range and real-world fast charging. SCC55® boosts EV battery energy density and drops charge times to less than a standard gas-station stop.

Applications

More power. Same footprint.

Unlock thinner designs and all-day power. Silicon-carbon battery technology powers the next generation of AI-enabled smartphones, laptops, and wearables without increasing device volume.The silicon battery era is here for consumer electronics.

Applications

Dynamic, rapid-response power.

Modern data infrastructure depends on backup and surge-response power to keep pace with dynamic AI workloads. Silicon batteries deliver rapid response and high-efficiency energy delivery while helping reduce strain on grid-connected power systems.

Applications

Lightweight energy for liftoff.

Make commercial electric flight viable. Practical electric flight requires lightweight, highly responsive energy storage. Silicon batteries support rapid power bursts and high-cycle durability, making electric aviation commercially viable and scalable.
