DOE AMO awards Amprius $1M to advance manufacturing technique of nano-wire silicon anodes


Amprius Applied sciences, a developer of ultra-high vitality density lithium-ion batteries with its Silicon Nanowire Anode Platform, was awarded a $1-million grant from the US Division of Power (DOE)’s Superior Manufacturing Workplace (“AMO”) for use to mature additional its course of for manufacturing nanowire-based silicon anodes. This represents the third grant from the DOE, following two earlier grants that Amprius obtained from the DOE’s Automobile Know-how Workplace.


This funding will help Amprius’ high-throughput source-less plasma deposition of structured silicon anodes for lithium-ion batteries. This system will allow Amprius to speed up the event of its high-volume manufacturing course of for its nanowire-based silicon anode utilizing a deposition system presently in use at the moment for manufacturing photo voltaic cells.

The grant will promote the maturation of its expertise to attain Amprius’ purpose of excessive quantity, low-cost ultra-high vitality density battery manufacturing that considerably will increase yield and throughput. The present vitality density ranges when utilizing Amprius’ silicon nanowire anode expertise are greater than 1,150 watt-hours (Wh)/liter and 450 Wh/kg.

This DOE grant extends Amprius’ monitor report of securing federal authorities funds to proceed to develop this expertise.


The 100% silicon nanowire anode is a direct substitute for graphite anodes. The remainder of the battery parts and manufacturing strategies leverage the established world provide chain for lithium-ion batteries.
