VANADIUM REDOX FLOW BATTERY ELECTRODE AND SINGLE CELL INCLUDING THE VANADIUM REDOX FLOW BATTERY ELECTRODE AND BATTERY INCLUDING THE SINGLE CELL

摘要

In the vanadium redox flow cell electrode according to the present invention, Are stacked and needle-punched, carbonized, A carbon fiber is formed by a unidirectional carbon fiber fabric disposed at a predetermined distance in a direction in which a vanadium electrolyte flows, and a carbon fiber felt in which carbon fibers are randomly arranged and intertwined. The lamination directions of the unidirectional carbon fiber fabrics laminated on the carbon fiber felt are all the same. When the present invention is used, the vanadium electrolyte passing through the electrode can cause the redox reaction sufficiently through the ion exchange membrane, and recovery to the electrolyte tank can be smoothly performed.
