Title:
REDOX FLOW SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2013/118998
Kind Code:
A1
Abstract:
The present invention relates to a redox flow secondary battery. The redox flow secondary battery of the present invention comprises a unit cell including a pair of electrodes made of a porous metal, wherein the surface of the porous metal is coated with carbon. According to the present invention, a redox flow secondary battery using porous metal electrodes uniformly coated with carbon is provided, thus improving conductivity of the electrodes, and the electrodes have surfaces uniformly coated with a carbon layer having a wide specific surface area, thus improving reactivity. As a result, capacity of the redox flow secondary battery and energy efficiency can be improved and resistance of a cell can be effectively reduced. Further, the electrodes are uniformly coated with a carbon layer, thus also improving corrosion resistance.
