US-based silicon battery anode material producer Group14 Technologies has announced a key performance benchmark for its SCC55 material—enabling silicon battery manufacturers to consistently achieve over 1,500 charge cycles, in some cases more than 3,000 cycles, across a range of applications.

The goal of the silicon battery industry has long been to meet 1,000 charge cycles, which is considered a benchmark for high-performance lithium-ion batteries.

Data recently gathered from more than 20 Group14 customers shows SCC55 exceeds 1,500 cycles across a range of applications, while maintaining higher energy density and fast charging.

This has implications for the total cost of ownership, particularly across battery-dominant sectors such as EVs, electric vertical takeoff and landing (eVTOL) aircraft and energy storage systems.

Group14’s SCC55 silicon battery material is compatible with a range of battery formats, including LFP, LMFP, and high-nickel chemistries.

“The data is clear: silicon batteries have crossed a critical threshold, and 1,500 cycles is the new 1,000,” said Rick Luebbe, CEO and co-founder of Group14 Technologies. “This performance benchmark for silicon batteries presents a new era of durability combined with higher energy density and faster charging for all types of rechargeable energy storage.”
