FIELD: electrical engineering. SUBSTANCE: cathode material is compound of general formula COxHy, where x = 0.06 to 0.5 and y = 0 to x. Cathode material is synthesized using chemical, electrochemical, or thermal oxidation of carbon material. The latter is chosen from series of carbon, graphite, FullerТs earth, or their mixture. EFFECT: improved discharge capacity and reduced toxicity of cathode material. 5 cl, 2 ex
