Energy-dense battery supports electric mobility

26 May 2025

The Silicon Anode Platform developed by Amprius now includes the 450 Wh/kg SiCore lithium-ion battery, an energy-dense cell offering 450 Wh/kg and 950 Wh/L.

This SiCore cell incorporates proprietary silicon anode material to deliver up to 80% more energy than conventional lithium-ion cells with graphite anodes. Extended flight time, greater range and improved system-level performance are enabled by the enhanced energy density within a compact, lightweight design.

Designed for extreme conditions to meet the demands of aviation and defense applications, the new SiCore cell maintains reliable performance across wide temperature ranges and mission-critical environments. It meets the demands of high- and medium-altitude platform stations as well as unmanned aerial vehicles. By providing longer range and greater payloads without increasing weight, this cell helps reduce total system cost. Operators can fly longer missions with fewer compromises, minimizing the need for additional batteries, fuel or equipment.

“What makes this SiCore cell different and noteworthy is that it brings that level of extreme performance into a cell chemistry and format that are ready to scale with the existing lithium-ion battery manufacturing processes and equipment in the industry,” said Dr. Kang Sun, CEO of Amprius Technologies.
