Safety, rate capability, and cycling performance of Moltech prismatic rechargeable cells

Abstract

It is shown that the Moltech rechargeable Li/S cells are acceptable under conditions defined in UL 1642. The cells can be charged at 3C charge rates without electronic protection. A specific capacity of 120 Wh/kg is obtained at a power of 1070 W/kg. 200 cycles to 80% of the 5th cycle capacity at varying charge and discharge rates has been obtained.
