Amprius Technologies, an NYSE-listed company developing silicon anodes for lithium-ion batteries, was awarded a USD 50 million cost-sharing grant from the US Department of Energy under the Bipartisan Infrastructure Law.

Amprius is currently aiming to demonstrate silicon nanowire anode technology manufactured at component and cell levels on multi-megawatt-hour-scale manufacturing lines. Through this demonstration, the company hopes to install and operate a first-of-its-kind large-scale production line for its ultra-high energy density batteries. 

Current pilot production of Amprius’ batteries indicates that battery cells using its proprietary anode technology can provide 2X the performance of commercially available graphite cells. The company’s commercially available batteries deliver up to 450 Wh/kg and 1,150 Wh/L, which are the highest known energy density cells available in the market.

The funding provided to Amprius is part of the first phase of a total of USD 7 billion in grants to be given by the US Bipartisan Infrastructure Law. This aims to expand domestic manufacturing of EV batteries and electrical grid batteries with a focus on increasing domestic processing of materials and components currently imported from other countries.
