Amprius Technologies has shipped its new 6.3Ah 21700 SiCore cell to a Fortune 500 company in the Light Electric Vehicle (LEV) sector for evaluation. The new cell sets a new standard in the industry for energy density in this widely used format.

With an energy density of 315 Wh/kg, the 6.3Ah SiCore cell builds on Amprius’ proven technology, delivering more than 25% more capacity than a standard 5.0Ah 21700 cell while maintaining a high-power 3C discharge rate. It achieves 800 cycles at 80% depth of discharge (DOD), extending battery lifespan and lowering replacement costs. Designed for seamless integration, its drop-in compatibility allows manufacturers to boost performance without the need for costly system redesigns.

While the initial focus for this 6.3Ah SiCore cell is on the LEV market, the high energy density and extended cycle life make it well-suited for a range of applications, including fixed wing aviation and AI applications such as robotics, Amprius said.

Amprius has secured manufacturing partnerships to support large-scale production, ensuring GWh-scale capacity to meet growing demand.
