Abstract
Provided is an electrode for an electrochemical device that has excellent peel strength and can ensure a high level of safety of an electrochemical device. The electrode for an electrochemical device includes a current collector and an electrode mixed material layer on the current collector. The electrode mixed material layer contains an electrode active material, a binder, and a foaming agent. The binder is a polymer including a diene monomer unit and/or nitrile group-containing monomer unit, and in which the total proportion constituted by the diene monomer unit and nitrile group-containing monomer unit is 10 mass % to 80 mass %. Volume resistivity Rof a laminate of the electrode mixed material layer and current collector at 25° C. is 0.1 Ω·cm to 200 Ω·cm, and a ratio of volume resistivity Rof the laminate at 350° C. relative to volume resistivity Rof the laminate at 25° C. is 10 or more.
