Recently, a research team led by Li Xianfeng and Zhang Huamin, researchers at the Energy Storage Technology Research Department of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, made new progress in the research of ion conductive membranes for alkaline zinc-based redox flow batteries. The research results were published online in "Advanced Functional Materials" (Adv.Funct.Mater.) on. Zinc-based redox flow battery energy storage technology uses abundant zinc as the negative active material. It has the characteristics of low cost, high safety, high open circuit voltage and environmental friendliness, and has good application prospects in the field of distributed energy storage. At present, the key problem of zinc-based flow batteries is the dendrites, accumulation and shedding of zinc anode, which leads to poor battery cycle stability. The film plays an important role in regulating zinc deposition morphology and inhibiting dendrite growth, thereby improving battery operation reliability. In the early stage, the research team could control the direction and morphology of zinc deposition by adjusting the negative charge properties of the porous ion-conducting membrane, thus greatly improving the area capacity of zinc-based liquid flow batteries and the cycle stability of the battery.
