PROBLEM TO BE SOLVED: To provide a binding agent which has high adhesion to a current collector, does not generate exfoliation during press processing, has high flexibility, and also has excellent binding properties and electrolyte resistance, and also to provide a lithium secondary battery having excellent charge-discharge behavior using an electrode manufactured using the binding agent.SOLUTION: A binding agent for an electrode of a lithium secondary battery contains a polyurethane aqueous dispersion comprising (A component) polyisocyanate, (B component) a compound having two or more active hydrogen groups, (C component) a compound having one or more active hydrogen groups and a hydrophilic group, and (D component) a chain extender. The (A component) contains polyisocyanate having three or more isocyanate groups. |
