In a galvanic element having a negative metal electrode, and non-aqueous electrolyte, the electrochemically reducible component of the positive electrode mass is a chromium oxide of the formula CrO.sub.x, where x lies in the range between 2 and 2.9.

High energy electrochemical current source

A galvanic element with negative light metal electrode and non-aqueous electrolyte, and having active material which is an organic sulfohalogenide.

Galvanic element with negative light metal electrode and non-aqueous

In a cell which uses a light metal negative electrode, the positive electrode mass has an electrochemically reducible component which is mainly Bi.sub.2 O.sub.3 and the electrolyte is a conductive salt dissolved in a mixture composed mainly of propylene carbonate and dimethoxyethane.

Light metal galvanic element

Lithium- or calcium-electrode elements are manufactured in air by first pretreating the electrode foil with a gas which reacts with the metal foil surface to form a temporary protective layer.

Manufacture of galvanic elements having lithium or calcium electrodes

Galvanic element with a negative electrode of a light metal, a non-aqueous electrolyte and a positive electrode containing arsenites, particularly silver and mercury arsenites, as the electrochemical reducible part of the electrode mass. The use of arsenites exhibit an especially high energy density and a very constant discharge potential during operation.

Galvanic element with a negative electrode of light metal, a non-aqueous

The electrochemically reducible component of the positive electrode mass is silver carbonate. The cell which includes this electrode and also a light-metal negative electrode. The battery made of such cells.
