Lithium Carbon Monofluoride: The Next Primary Chemistry for Soldier Portable Power Sources
Abstract
The US Army is interested in a low cost, high energy density primary lithium power source for use as the energy source for field charging units, for use in advanced man portable electronic equipment, and for unmanned and unattended systems. Lithium metal can provide a theoretical 13 Kilowatthours/ kilogram based on the metal. This is ten times greater than the theoretical specific energy of zinc. It is imperative that the government invests in this chemistry and reduces the burden on the soldiers. Current lithium-ion rechargeable battery technologies have a specific energy of 170 Watthours/ kilogram and state-of-the-art primary lithium-based systems have a specific energy approaching 200 Watt-hours/kilogram. A weight burden is added to the user as a result of this low specific energy and additional logistic support is required for recharging. It is imperative that the novel lithium power energy source have a superior specific energy (>400 Watt-hours/kilogram) and a moderate specific power (>50 Watts/kilogram).
