Abstract

CARBOXYMETHYLCELLULOSE OR SALT THEREOF FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY The present invention is aimed to provide carboxymethylcellulose or a salt thereof for a nonaqueous electrolyte secondary battery, an electrode composition containing the same for a nonaqueous electrolyte secondary battery, an electrode for a nonaqueous electrolyte secondary battery, and a nonaqueous electrolyte secondary battery, with a small reduction in the capacity even when charging and discharging are repeated, and with high durability. The carboxymethylcellulose or the salt thereof is used as a binder for an electrode of a nonaqueous electrolyte secondary battery, in which the degree of substitution with carboxymethyl of the carboxymethylcellulose or the salt thereof is 0.5 to 1.5, and a thermal rate of change T that is a difference (WB - WA) between a thermal weight reduction rate WA at a thermal decomposition start point and a thermal weight reduction rate WB at a thermal decomposition end point measured by a thermogravimetric-differential thermal analyzer is 45% or lower.
