Flow battery carbon electrode functionalization method and flow battery electrode thereof

The invention discloses a functionalization method for a carbon electrode of a flow battery and an electrode of the flow battery, relates to the field of electrochemical energy storage flow batteries, and aims to solve the problems of low loading capacity and low utilization rate of active substances on an electrode base material. Functional modification is carried out on the surface of the flow battery electrode by an active substance and a binder solution under the action of external pressure and a spray gun. A common carbon electrode material for a flow battery is a loose three-dimensional material such as a carbon felt, a graphite felt, carbon paper and carbon cloth, and the material is relatively high in conductivity and physical and chemical stability and is often used as the electrode material for the flow battery, but the activity of surface functional groups is relatively low, the number of types is relatively small, and the activity of a chemical reaction on the surface of an electrode is influenced
