A non-aqueous cell having a lithium anode is made abuse resistant by sandwiching and enclosing a thin substantially perforation-free copper foil or sheet between layers of lithium whereby the copper is isolated from the cell electrolyte.

Cell having improved abuse resistance

A cathodic active material is described utilizing the periodates of heavy metals and preferably of silver. These materials are particularly suitable for use as positive electrodes in nonaqueous electrolyte cells and such electrodes and the cells are described. A method for fabrication of the active material into cathodes is included.

Metal periodate organic electrolyte cells

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.
