Abstract: A negative electrode 10 for a nonaqueous secondary battery has an active material layer 12 containing active material particles 12a. The particles 12a are coated at least partially with a coat of a metallic material 13 having low capability of lithium compound formation. The active material layer 12 has voids formed between the metallic material-coated particles 12a. When the active material layer 12 is imaginarily divided into equal halves in its thickness direction, the amount of the metallic material 13 is smaller in the half closer to the negative electrode surface than in the other half farther from the negative electrode surface. The weight ratio of [the particles/the metallic material] in the half closer to the negative electrode surface is preferably higher than that in the other half farther from the negative electrode surface.

Abstract: A negative electrode for nonaqueous secondary batteries is disclosed. The negative electrode has a pair of current collecting surface layers of which the surfaces are adapted to be brought into contact with an electrolyte and at least one active material layer interposed between the surface layers. The active material layer contains particles of an active material having high capability of forming a lithium compound. The material constituting the surfaces is preferably present over the whole thickness of the active material layer to electrically connect the surfaces so that the electrode exhibits a current collecting function as a whole. The surface layers each preferably have a thickness of 0.3 to 10 ?m.

Abstract: An anode for nonaqueous secondary batteries is disclosed. The anode has a pair of current collecting surface layers of which the surfaces are adapted to be brought into contact with an electrolytic solution and at least one active material layer interposed between the surface layers. The active material layer contains particles of an active material having high capability of forming a lithium compound. The material constituting the surfaces is preferably present over the whole thickness of the active material layer to electrically connect the surfaces so that the electrode exhibits a current collecting function as a whole. The surface layers each preferably have a thickness of 0.3 to 10 ?m.

Abstract: Disclosed is a negative electrode for a nonaqueous secondary battery included of a current collector and an active material structure containing an electro-conductive material having low capability of forming a lithium compound on at least one side of the current collector, the active material structure containing 5 to 80% by weight of active material particles containing a material having high capability of forming a lithium compound. The active material structure preferably has an active material layer containing the active material particles and a surface coating layer formed on the active material layer.
