Abstract
A negative electrodefor a nonaqueous secondary battery has an active material layercontaining active material particles. The particlesare coated at least partially with a metallic materialhaving low capability of lithium compound formation. The active material layerhas voids located between the metallic material-coated particleswith a void fraction of 15% to 45%. The metallic materialon the surface of the particles is preferably present throughout the thickness of the active material layer. The active material particlesare preferably of a silicon-based material. The active material layerpreferably contains 1% to 3% by weight of an electroconductive carbon material based on the weight of the active material particles
