The utility model relates to an electrode for a secondary battery, and a secondary battery and a wirecable-type secondary battery including the same. The electrode for the secondary battery comprises a current collector, an electrode active material layer, a porous polymer layer and a first porous support layer, wherein the electrode active material layer is formed on one surface of the current collector, the porous polymer layer is formed on the electrode active material layer, and the first porous support layer is formed on the porous polymer layer. According to the electrode for the secondary battery in a piece form, the support layers are arranged on at least one surface of the electrode, thereby, a wonderful improvement of the flexibility is shown, even if strong external force is exerted on the electrode, the electrode active material layer can still be prevented from falling off the current collector, therefore, the battery capacity is prevented from declining, and the cycle life characteristic of the battery is improved. |
