Discharge properties of a lithium/sulfur cell at body temperature

Abstract

To investigate the feasibility of a Li/S cell for application to medical devices, the discharge properties of Li/S cells were investigated at 36.5 degrees C. A Li/S cell has the first discharge capacity 1158 mA h (g-S)(-1) at body temperature, whose cathode is composed of sulfur, carbon black and PVdF. The Li/S cells were discharged at various current densities to evaluate the rate capability, and the cycle performance at 100 mA g(-1) current density was also studied compared with previous reports.
