Negative electrode of nonaqueous lithium-ion secondary battery and nonaqueous lithium-ion secondary battery using same

Abstract

A negative electrode which includes graphite particles and which is capable of imparting superior input resistance characteristics to a nonaqueous lithium-ion secondary battery is provided. The negative electrode of a nonaqueous lithium-ion secondary battery disclosed herein includes graphite particles as negative electrode active materials and a supported material being supported by the graphite particles. The graphite particles have phenolic hydroxy groups. The supported material has surface hydroxy groups. A ratio of an amount B (mmol/g) of the surface hydroxy groups in the supported material to an amount A (mmol/g) of the phenolic hydroxy groups in the graphite particles is 30 or more and 150 or less.
