Abstract
A composite anode includes particles of an alkali metal alloy, a carbonaceous material powder and a binder and used for nonaqueous secondary batteries in which an alkali metal is used as an anode active material and a solution of an electrolyte in an organic solvent is used as an electrolyte solution, wherein the carbonaceous material powder contains oxygen atoms and the oxygen content is in the range of 1 to 5% by weight. A method for producing this composite anode includes the steps of mixing a solution of a binder comprising a copolymer of monomers mainly composed of olefins in an aromatic solvent with the alkali metal alloy particles and the carbonaceous material powder, coating the mixture on an electrode substrate and molding the coated substrate.
