Temperature characteristics of nonaqueous Li-O2 batteries

Discharge/charge characteristics of Li-O-2 batteries at a test temperature of 343 K, using Super P carbon electrodes, have been explored in this paper based on ether-based electrolytes. Compared with ambient temperature, high temperature significantly influences the discharge/charge process of Li-O-2 batteries since discharging capacity increases at about 80 % and charging voltage plateau decreases from 4.2 to 3.5 V. The stability of stainless steel mesh with electrolyte at 343 K has been researched using cyclic voltammetry. This paper lays the bases for further research on Li-O-2 batteries in high-temperature areas.
