ABSTRACT:
A negative electrode for a non-aqueous electrolyte secondary cell includes a current collector an, formed on a surface or both surfaces thereof, an active material structure containing an electroconductive material with a low capability of forming a compound with lithium, and the active material structure includes 5% to 80% by weight of active material particles containing a material having a high capability for forming a compound with lithium. The active material structure can include an active material layer containing the active material particles and a surface-covering layer on the active material layer.
