Abstract
This invention relates to a novel primary battery comprising at least one positive plate composed of cobalt, oxides and their mixtures, and at least one negative plate having a metal selected from the group of light metals, said plates being disposed in an electrolyte comprising an organic solvent selected from the group consisting of tetrahydrofuran, N-nitrosodimethylamine, dimethyl sulfite, propylene carbonate, gamma-butyrolactone, dimethyl carbonate, dimethoxy ethane, aceto-nitrile and the mixtures thereof, and having dissolved therein soluble salts of the light metals, for example, the perchlorates, hexafluorophosphates, tetrafluoroborates, tetrachloroaluminates, and hexafluoro arsenates of lithium.
Claims5
A high energy density cell comprising a positive electrode composed of a cobalt oxide positive electrode material selected from the group consisting of Co.sub.2 O.sub.3 and Co.sub.3 O.sub.4 and mixtures thereof;
- a negative electrode consisting of a metal selected from the group of light metals;
- said electrodes being disposed in an electrolyte comprising an organic solvent selected from the group consisting of tetrahydrofuran, N-nitrosodimethylamine, dimethyl sulfite, propylene carbonate, gamma-butyrolactone, dimethyl carbonate, dimethoxyethane, acetonitrile, and the mixtures thereof, and having dissolved therein soluble salts of the light metals, wherein said soluble salts are selected from the group consisting of perchlorates, hexafluorophosphates, tetrafluoroborates, tetrachloroaluminates, and hexafluoroarsenates.
