A High Performance, Low Temperature Li-ion Battery Using a Metal Alloy Anode

"This BMDO Phase I proposal is aimed at developing a high performance Li-ion battery using a metal alloy anode for low-temperature applications. The anode materials are based on nano-structured metal alloys that directly address two major limitations ofcommercial graphite anodes: First, the materials allow faster lithium diffusion than in graphite. Second, the materials are compatible with electrolytes that have better low-temperature properties than currently-used ethylene carbonate-based electrolytes.In Phase I, we will demonstrate that the combination of nano-structured metal alloy and high performance electrolyte will give a low temperature capacity far superior to the commercial graphite-based anodes. In Phase II, we will further develop Li-ionprototype batteries for low-temperature applications. If successful, the proposed system will significantly improve the low-temperature performance of Li-ion batteries and expand their application to the defense and space industries where a near-termapplication is expected. Such batteries are critical for the success of the National Missile Defense, a plan that becomes increasingly urgent given the increased threats by terrorist countries and organizations. On a broader scale, T/J Technologies'tin-based anode materials are developed for use in lithium rechargeable batteries including lithium ion and lithium polymer cells. Potential customers include battery manufacturers and battery m
