POSITIVE ACTIVE MATERIA FOR ELECTROCHEMICAL GENERATOR, AND GENERATOR UNDERSTANDING THE SAME

摘要

The invention relates to a positive active material for an electric cell. Such an active material is constituted by a vitreous compound which results from the addition of a small quantity of silica to at least one electrochemically reducible metal oxide. Application to electric cells with non-aqueous electrolyte, the negative electrodes of these cells being based on an alkali or alkali-earth metal.
