Amprius says it has signed deals with three electric aircraft developers for the purchase of its next-generation lithium-ion battery cells, which pack an ultra-high energy density of 450 Wh/kg. The California-based battery developer did not disclose the identity of its customers or the volume of the new orders, only that it will be delivering custom battery cells to three “premier electric aviation manufacturers.” 

The 450 Wh/kg battery platform is designed to support products with higher power needs, including electric airplanes and new eVTOL aircraft, which use significantly more power to take off and land than their conventional fixed-wing counterparts. Featuring the company’s proprietary silicon nanowire anode technology, the 450 Wh/kg battery system packs a higher energy density than any commercially available lithium-ion batteries, according to Amprius.
