An alkali metal, solid cathode, nonaqueousnelectrochemical cell capable of delivering high currentnpulses, rapidly recovering its open circuit voltage andnhaving high current capacity, is described. The statednbenefits are realized by the addition of at least onennitrate additive to an electrolyte comprising an alkalinmetal salt dissolved in a mixture of a low viscositynsolvent and a high permittivity solvent. A preferrednsolvent mixture includes propylene carbonate,ndimethoxyethane and an alkali metal nitrate, alkalinenearth metal nitrate and/or an organic alkyl nitratenadditive. |
