Amprius Technologies has achieved a new battery energy density breakthrough of 500 Wh/kg with its Li-ion cell, the Silicon Anode Platform. Mobile Power Solutions, an independent testing house, verified the Silicon Anode Platform's energy density performance.

The results indicate that this cell model provides >504 Wh/kg and >1321 Wh/l at 25°C. Amprius Technologies Chief Operating Officer Jon Bornstein joins the Here’s an Idea Podcast to discuss the results of the test and what it means for electric-powered aircraft.
