NEGATIVE ELECTRODE MATERIAL FOR NON-AQUEOUS SECONDARY BATTERIES, NEGATIVE ELECTRODE FOR NON-AQUEOUS SECONDARY BATTERIES, AND NON-AQUEOUS SECONDARY BATTERY

A negative electrode material for nonaqueous secondary batteries, the negative electrode material comprising carbonaceous particles (A) and silicon oxide particles (B), the carbonaceous particles (A) having a 10%-particle size displacement pressure of 10 MPa or less, the 10%-particle size displacement pressure being measured using a micro-compression testing machine by a specific measuring method, the silicon oxide particles (B) having a median diameter (D50) of 0.8 µm or more and 20 µm or less. It is preferred that the content of the silicon oxide particles (B) is less than 30% by weight of a total content of the carbonaceous particles (A) and the silicon oxide particles (B).
