PURPOSE:To prevent deterioration in the battery performance due to decrease in the amount of organic electrolyte or breakdown of the battery due to abnormal increase in gas pressure, by adding polyphenelene or its derivertive to the anode. CONSTITUTION:The cathode 1 produced by punching into a predetermined size from lithium plate is pressed and attached to the internal bottom face of the cathode can 10. And the anode 2 produced by pressure forming of mixed powder composed of 80% by weight of molybdenum trioxide as the active material for the anode, 6% by weight of acetylene black as conductive material, 4% by weight of fluororesin powder as binding agent, and 10% by weight of polyphenelene powder is arranged on the internal bottom face of the anode can 20. Reference numeral 3 denotes a separator of nonwoven fabric of polypropylene impregnated with organic electrolyte prepared by dissolving 1mol/1 of lithium perchlorate as solute in the mixed solvent composed of propylene cabonate and 1.2 dimethoxyethane. By adding polyphnelene to the anode as described above, the charging voltage becomes constant in the vicinity of about 4.0V and the charging voltage does not rise anymore as shown by the curve A in the adjoining graph. |
