NEGATIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, METHOD FOR MANUFACTURING SAME AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

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 µm.
