ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTIC SECONDARY BATTERY, NEGATIVE ELECTRODE MOLDED ARTICLE AND NONAQUEOUS ELECTROLYTIC SECONDARY BATTERY

摘要

Provided is an active material for a non-aqueous electrolytic secondary battery including silicon particles or silicon compound particles having excellent cycle properties when using a liquidity and non-aqueous electrolytic secondary battery. The active material for the non-aqueous electrolytic secondary battery comprises silicon particles or silicon compound particles, and silica adhesion particles having spherical silica minute particles attached on the surface, wherein the average particle diameter of the spherical silica minute particles is 5 nm to 1.00 μm; the value of the size distribution D_90/D_10 is under three; and the average compactness is 0.8 to 1.
