Abstract
A non-aqueous electrolyte cell is disclosed. As main components thereof, are employed a positive electrode having as an active material copper oxide which is obtained by pyrolyzing copper hydroxide prepared by mixing an aqueous solution of copper salt and an aqueous solution of alkali hydroxide, a negative electrode having as an active material lithium or lithium alloy and a non-aqueous electrolyte. A method of manufacturing a non-aqueous electrolyte cell is also disclosed. The method comprises a first step of producing copper hydroxide by mixing an aqueous solution of copper salt and an aqueous solution of alkali hydroxide and causing chemical reaction between the two, a second step of producing copper oxide by pyrolyzing the above copper hydroxide, and a third step of manufacturing a positive electrode employing the above copper oxide as an active material for the positive electrode.
