Amprius Technologies Inc. (NYSE: AMPX) introduced its second-generation SiCore battery platform. The silicon-anode lithium-ion cell is rated at 500 Wh/kg for uncrewed electric aviation systems (UAS) and other applications where battery mass directly limits mission endurance.

According to the company, the SiCore 500 cell achieves that specific-energy figure at a continuous 1C discharge rate and, crucially, can be built using conventional lithium-ion manufacturing equipment. Commercial availability is expected in the fourth quarter of 2026.
