Electrode for electrochemical device, electrochemical device, and method for manufacturing electrode for electrochemical device

摘要

An electrode for an electrochemical device includes a current collector and an electrode layer. The current collector has a main face and a side face. The side face has a concave-convex shape whose convex part is constituted by a projection extending along the main face. The projection is formed along a periphery of the electrode layer, forming a support portion. The electrode layer contains active material and is formed on and in contact with the main face including a surface formed by the support portion. The electrode is capable of mitigating the concentration of current at the edges of the electrode layer.
