Amprius Technologies, a manufacturer of lithium-ion batteries that use silicon anode technology, has shipped its new 6.3 Ah SiCore cell to an unnamed customer that is in the light electric vehicle segment, a member of the Fortune 500 list.

The battery is intended for applications that require more efficient energy storage solutions, the company said, citing fixed-wing aviation and applications such as robotics as potential markets in addition to the EV market.

Offering drop-in compatibility, the new SiCore cell delivers specific energy of 315 Wh/kg. It delivers over 25% more capacity than a standard 5.0 Ah 21700 cell while maintaining a high-power 3C discharge rate, the company said. In addition, the manufacturer’s specifications indicate that it can achieve 800 cycles at 80% depth of discharge. This serves to extend battery lifespan and lower replacement costs, Amprius stated.

The new cell “has attracted strong interest from leading OEM manufacturers because it delivers a significant improvement in battery performance,” said Dr. Ionel Stefan, the company’s CTO.

Founded in 2008, Amprius is headquartered in Fremont, California, where it also has its research and development laboratory as well as a MWh-scale manufacturing facility for the fabrication of silicon anodes and cells.

The company recently announced an expanded contract manufacturing agreement. CEO Kang Sun said that gigawatt-hour-scale production capacity will be required “to deliver the high-performance silicon batteries that our customers rely on to power their most advanced electric mobility applications.”
