Problems solved by technology
[0004] The invention provides an application of a liquid metal zinc alloy in a zinc-based flow battery. The negative electrode uses a liquid metal zinc alloy to solve the problem of zinc dendrites in the charging process of the negative electrode, thereby improving the safety and stability of the battery. It can flow, which solves the problem of limited surface capacity of the battery
However, in the present invention, liquid gallium-zinc alloy is used to eliminate the influence of zinc dendrites during battery operation on the one hand, and to solve the problem of surface capacity limitation caused by zinc deposition on electrodes during charging on the other hand.
