Amprius Technologies (Amprius), a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, has exited technical engagement and moved into internal qualification, securing a purchase order from an eVTOL (electric vertical take-off and landing) manufacturer for custom silicon anode cells. Amprius’ advanced cells now serve all major segments of the growing aviation market for electric mobility.
The eVTOL manufacturer strategically selected Amprius’ state-of-the-art cells to expand flight range and accelerate time-to-market. The custom cells are based on Amprius’ ultra-high-power, high-energy lithium-ion batteries announced in August.
Leveraging Amprius’ advanced material system expertise, the 400-Wh/kg cell is capable of an impressive continuous discharge rate of 10C. The new cell brings unprecedented benefits to the eVTOL industry, providing unmatched propulsion power and energy to meet the rigorous demands during take-off, cruise and landing without sacrificing performance. In addition, the new ultra-high-power cell features ultra-fast charging (UFC) capabilities, allowing it to reach 80% charge in six minutes or less, facilitating expanded flight operations with swift turn-around times.
The agreement is contingent upon the successful qualification of sample custom cells to be delivered later this year. Following successful qualification of the cells, the eVTOL manufacturer would receive an increased number of custom samples in early 2024 for its demonstrator integration. In parallel with the integration, Amprius expects to engage in discussion for a long-term volume purchase agreement to support the eVTOL manufacturer’s pre-production units in 2025 and beyond. The future volume purchases would be supported by Amprius’ Brighton, Colorado gigawatt-hour scale factory.
