PROBLEM TO BE SOLVED: To provide a binder composition for the electrode of a power storage device in which the degree of capacity degradation due to repetition of charge/discharge cycle is low, even if an active material having a large discharge capacity and a large volume change incident to charge/discharge is used.SOLUTION: In the binder composition for the electrode of a power storage device containing at least a polymer (A) and a liquid medium (B), the polymer (A) is a polymer having a repeating unit (a1) derived from a polymerizable unsaturated compound having a 3-6 membered cyclic ether structure, and a repeating unit (a3) derived from a polymerizable unsaturated compound having a chain ether structure, or a polymer having a repeating unit (a2) derived from a polymerizable unsaturated compound having a 4-6 membered cyclic ether structure. |
