High Energy, Extended Temperature Range Lithium Ion Battery with Nonflammable Electrolyte

Foster-Miller proposes to develop high voltage lithium ion batteries having nonflammable electrolyte and capable of delivering high power at temperatures from 70¿C to -40¿C. These lightweight rechargeable batteries will be able to operate in the coldtemperatures at high altitudes, greatly advancing the development of power sources for applications such as all-electric UAVs, reusable launch vehicles, and satellites. (P-030206) These rechargeable batteries are expected to become the principal portable power sources across a broad spectrum of military applications by providing light weight, low temperature high power capability comparable to that which is currently onlyavailable from single use primary batteries. Such applications will include satellite communications, GPS navigation and weapons targeting electronics. Changeover to rechargeable batteries will greatly ease logistical burdens of battlefield deploymentand resupply. Similar impacts are expected in specialty industrial applications requiring extended temperature range-capable, light weight high power batteries.
