Electrochemical generator. [Li/Li perchlorate in organic solvent/Cu oxide, Ag chromate, Pb chromate, or fluorinated C]

Patent ·
OSTI ID:7348270

This invention relates to high-energy-density electrochemical generators of the alkaline, more particularly lithium, negative-electrode type. An electrolyte whose solvent contains 1--3 dioxane, dioxolane or propylene oxide, preferably mixed with propylene carbonate or ethylene carbonate, is utilized. This electrolyte has excellent conductivity, even at a relatively slight concentration of the solute. Lithium perchlorate is preferred as the solute; and copper oxide, monovalent silver chromate, lead chromate, fluorinated carbons, polymerized fluorinated carbons or mixtures of these latter with metal compounds are preferred as active positive material.
