Development of a High Capacity Lithium-Ion Battery for a Navy Aircraft
Abstract
In response to the Navy's requirement for a lighter, higher capacity, secondary battery, Mine Safety Appliances (MSA) Company designed and built an experimental lithium-ion "drop-in" replacement battery for demonstration of its performance in the Pioneer aircraft. Lithium ion technology using a lithiated cobalt dioxide positive electrode, graphitized carbon negative electrode and liquid organic electrolyte has demonstrated a significant enhancement in performance over other rechargeable systems such as nickel-cadmium and nickel-metal hydride in comparable applications. Key features of the lithium ion system include higher gravimetric and volumetric energy densities, good charge retention (to maximize readiness), and zero memory effect. Such benefits outweigh a higher unit cost and the need for more stringent charge/discharge control. Design of the cells and battery, and preliminary battery test results are described.
