Abstract

The following aspects (1) to (4) of the present invention can provide an electrode for nonaqueous electrolyte battery having excellent safety and charged storage properties and good high rate charge-discharge properties. (1) An electrode for nonaqueous electrolyte battery comprising a particulate active material having a porous film formed thereon. (2) An electrode for nonaqueous electrolyte battery comprising an active material having a filler held in pores. (3) An electrode for nonaqueous electrolyte battery comprising an active material which undergoes volumetric expansion and shrinkage during charge-discharge, having a filler held in pores. (4) The electrode for nonaqueous electrolyte battery according to Claus (1), wherein said porous film is an ionically-conductive film.
