Abstract
An objet of the invention is to provide a non-aqueous electrolyte secondary battery superior in input-output characteristics even at a low temperature. To achieve the object, hybrid particles (carbon material) satisfying certain conditions, and composed of graphite particles and carbon particles with a primary particle size from 3 nm to 500 nm, preferably as well as amorphous carbon, are used as a negative electrode active material for a non-aqueous electrolyte secondary battery, so that the input-output characteristics of a non-aqueous electrolyte secondary battery at a low temperature can be improved remarkably.
