Amprius Technologies Awarded Department of Energy Funding Grant for Advanced Battery Manufacturing

This funding will support Amprius’ high-throughput source-less plasma deposition of structured silicon anodes for lithium-ion batteries. The program will enable Amprius to accelerate the development of its high-volume production process for its nanowire-based silicon anode using a deposition system presently in use today for manufacturing solar cells.

The grant will promote the maturation of its technology to achieve Amprius’ goal of high volume, low-cost ultra-high energy density battery production that significantly increases yield and throughput. The current energy density levels when using Amprius' silicon nanowire anode technology are over 1,150 watt-hours (Wh)/liter and 450 Wh/kg.

This DOE grant extends Amprius’ track record of securing federal government funds to continue to develop this critical technology.

As noted by the DOE, the AMO-awarded projects will help to advance clean energy manufacturing in the United States, with the goal of driving economy-wide reductions in carbon emissions.

With support from the DOE as part of the national agenda, Amprius benefits from this non-dilutive financing to complement its growth plan.

“We are proud to be awarded another grant from the Department of Energy’s Advanced Manufacturing Office,” said Dr. Kang Sun, Chief Executive Officer of Amprius. “Our ultra-high density silicon nanowire anode batteries are well-suited to meet the DOE’s clean energy manufacturing objectives. The continued support from the Department of Energy for Amprius further validates our pioneering technology and reinforces the need to quickly scale our high-volume production to meet demand.”
