Abstract

An organic electrolyte cell comprising a light metal as the anode active material, and copper powder-added manganese dioxide as the cathode active material.

Claims

1. An organic electrolyte cell comprising lithium as the anode active material, and copper powder-added manganese dioxide as the cathode active material.

2. An organic electrolyte cell according to claim 1 wherein the copper powder is added to the manganese dioxide in an amount of 1-20% by weight of a total of the ingredients for the cathode.

3. The cell according to claim 1 wherein the organic electrolyte consists of propylene carbonate and dimethoxyethane in the ratio of 1:

1, by volume and 1 mole per liter of LiCl₄.
