Title: REDOX FLOW SECONDARY BATTERY AND ELECTRODE THEREOF
Abstract:
Provided is a redox flow secondary battery including a positive electrode, a negative electrode facing the positive electrode, and an ion exchange membrane provided between the positive electrode and the negative electrode. At least one electrode of the positive electrode and the negative electrode has a metal protective film that has an opening and a carbon electrode that includes carbon fibers in this order from the ion exchange membrane side. The height of the projecting peak portion of the surface of the metal protective film, which is in contact with the ion exchange membrane, is 0. 1-2 μm.
