摘要：
Provided is a binder capable of realizing a lithium secondary battery that includes a negative electrode including a negative-electrode active material layer containing at least one of silicon and a silicon alloy as a negative-electrode active material and also containing a binder and has an excellent charge-discharge cycle characteristic. The binder for the lithium secondary battery contains a polyimide resin that is formed by imidizing either a tetracarboxylic acid or a tetracarboxylic anhydride and a diamine, the polyimide resin having a hydrolyzable silyl group.
