NEGATIVE ELECTRODE FOR SECONDARY BATTERY, AND SECONDARY BATTERY USING SAME

WIPO Patent Application WO/2011/068097

A1

Disclosed is a negative electrode for a secondary battery, which is capable of sufficiently improving input/output characteristics of a secondary battery such as cycle life, while having practical characteristics such as discharge capacity, initial efficiency, capacity retention rate and reliability (safety) that are required for use on vehicles such as an HEV. Specifically disclosed is a negative electrode for a secondary battery, which comprises an active material layer in which a negative electrode active material is integrated by a binder. The negative electrode material is obtained by firing a coke material which is obtained by blending one or more kinds of green coal or petroleum coke and one or more kinds of calcined coal or petroleum coke at a mass ratio of from 90:10 to 10:90, and to which a phosphorus compound or a phosphorus compound and a boron compound are added, while essentially containing the phosphorus compound, per 100 parts by mass of the green coke and calcined coke in total. The binder is composed of a polyimide resin.
