In galvanic high-energy cells with negative light-metal electrodes (e.g., Li) and electrolyte component solvents including ether with a CH bond activated by the neighboring groups -O-, =CO or =N, the formation of explosive peroxides is inhibited by adding stabilizer substances to the electrolyte in amounts of about 100 ppm. These stabilizer substances can include alkyl-substituted phenols, especially 2,6-di-tert-butyl-4-methylphenol, and readily oxidizable organosulfur and organophosphorus compounds such as trimethylphosphite. This permits safe handling of the cells, even under unusual operating conditions (e.g., prolonged overcharging at high current). |
