US Army, Brown Univ. partner to study SEI on silicon anodes to extend Li-ion battery life

By mmillikin Through a Cooperative Research and Development Agreement (CRADA) negotiated by the US Army Research Laboratory (ARL) Technology Transfer and Outreach Office, ARL and Brown University researchers are attempting to address the difficulty of characterizing and then engineering the solid electrolyte interphase (SEI) layer that forms on the anode of lithium ion batteries, with particular emphasis on experimental silicon anodes with very high capacities for lithium.

The Army is working to replace all alkaline and nickel metal hydride field batteries with Li-ion batteries. “The Army is developing hybrid vehicles for use on the battlefield, and that means they will also use Li-ion
