Abstract
The invention provides a treatment method of a vanadium battery carbon felt electrode. The treatment method comprises the following steps of: (1) soaking the carbon felt electrode by concentrated sulfuric acid, and then washing by clear water; (2) putting the cleaned carbon felt electrode into mixed solution of hydrochloric acid and ferric chloride, and soaking; (3) taking a saturated calomel electrode as a reference electrode and a platinum electrode as a counter electrode, and scanning within the range of 1-2V; (4) taking out the carbon felt electrode, washing by clear water, and then putting the carbon felt electrode into saturated oxalic acid solution with the mass percent concentration of 88%; and (5) taking out the carbon felt electrode, cleaning and drying. Compared with the prior art, the vanadium battery carbon felt electrode obtained by the treatment method has better reversibility and better cycling stability.
