Patent ID: 7811709

Claim:
A negative electrode for a nonaqueous electrolyte secondary battery, comprising: a current collector; an active material layer on the current collector, the active material layer containing an electro conductive material having a first capability of forming a lithium compound on one side of the current collector, the active material layer containing 5 to 80% by weight of active material particles containing a material having a second capability of forming a lithium compound that is greater than the first capability; and a surface coating layer located on and completely covering the active material layer, so that falling off as a result of pulverization due to intercalation and deintercalation of lithium is prevented, and the surface coating layer has a polycrystalline structure with a large number of micropores extending in a thickness direction normal to a plane of the surface coating layer and allowing a nonaqueous electrolyte to pass therethrough.
