| titleOfInvention | Difunctional negative electrode and its application as all-vanadium redox energy storage battery negative electrode |
| abstract | A difunctional negative electrode for an all-vanadium redox energy storage battery negative electrode includes a carbon matrix material and a Bi-containing electro-catalyst modifying the surface of the carbon matrix material. The negative electrode is suitable for being used as the negative electrode of the all-vanadium redox energy storage battery, can greatly improve the electrocatalytic activity and electrochemical reversibility of an electrode material on a V<2+>/V<3+> redox reaction, and decreases the charge transfer resistance; and the negative electrode has high hydrogen evolution overpotential, can inhibit a hydrogen evolution reaction, and prolongs the work life of the battery. The difunctional negative electrode improves the voltage efficiency and energy efficiency of the all-vanadium redox energy storage battery, so the working current density of the battery is improved, and the weight, the size and the cost of the battery with same output power are greatly reduced. |
