Lithium Air Rechargeable Battery

Quallion LLC was awarded contract No. W56HZV-11-C-0047 under Army topic No. A10-139 entitled"Lithium Air Rechargeable Battery."The solicitation calls for a lithium air battery with a much higher energy density and longer duration energy storage system to replace lead acid or lithium ion batteries in non-primary power systems and silent watch applications. To achieve the objective in Phase II, Quallion proposes two major changes to the lithium-air system to increase energy density and cycle stability. These developments will reduce the overall weight of the cell by 50% and stabilize the cell performance increasing energy density toward 1000 Wh/kg and cycle life toward 200 cycles. In addition, the proposed technology will provide potentially limited self-discharge, good charge/discharge efficiencies, low temperature performance, and a long calendar life of lithium batteries.
