摘要
The purpose of the present invention is to provide a lithium-ion battery that exhibits excellent long-term life properties, does not suffer from rapid capacity degradation, and exhibits excellent charging/discharging characteristics in low-temperature environments. The present invention is directed to a negative electrode for a lithium ion battery, which comprises a negative electrode active material containing a graphite or an amorphous carbon, conductive additives containing a graphite, and a binder; and a lithium ion battery comprising this negative electrode. The negative electrode is characterized in that the negative electrode active material has a spherical or massive shape; the conductive additives have a platy shape; and part of an edge surface of the conductive additives contacts a surface of the negative electrode active material.
