The invention discloses a zinc-bromine flow battery carbon-plastic bipolar plate as well as a preparation method and application thereof, and belongs to the technical field of electrochemical energy storage. The method comprises the following steps: dispersing a nitrogen-doped hollow carbon nanobox, spraying the nitrogen-doped hollow carbon nanobox on the positive electrode side of a carbon-plastic bipolar plate, and drying to obtain a positive electrode carbon-plastic bipolar plate modified by the nitrogen-doped hollow carbon nanobox; and dispersing the boron-nitrogen co-doped carbon, spraying the boron-nitrogen co-doped carbon on the negative electrode side of the pretreated carbon-plastic bipolar plate, and drying again to obtain the boron-nitrogen co-doped carbon modified negative electrode carbon-plastic bipolar plate. On the positive electrode side, the nitrogen-doped hollow carbon nanobox catalyzes bromine reaction through nitrogen doping, and the overpotential is reduced; the hollow structure adsorbs bromine species and inhibits bromine permeation by utilizing the charge effect, so that self-discharge is reduced. On the negative electrode side, boron-nitrogen co-doped carbon utilizes B-N zinc-loving sites to guide zinc to be uniformly and compactly deposited, and dendritic crystals are inhibited; and hydrogen evolution is inhibited through charge regulation and control. The two synergistically improve the bromine resistance, reaction kinetics and dendritic crystal inhibition capability of the carbon-plastic bipolar plate.

This invention discloses a carbon-plastic bipolar plate for a zinc-bromine flow battery, its preparation method, and its application, belonging to the field of electrochemical energy storage technology. The method includes: dispersing nitrogen-doped hollow carbon nanotubes and spraying them onto the positive electrode side of a carbon-plastic bipolar plate; after drying, a nitrogen-doped hollow carbon nanotube-modified positive electrode carbon-plastic bipolar plate is obtained; dispersing boron-nitrogen co-doped carbon and spraying it onto the negative electrode side of a pretreated carbon-plastic bipolar plate, after drying again, a boron-nitrogen co-doped carbon-plastic negative electrode carbon-plastic bipolar plate is obtained. On the positive electrode side, the nitrogen-doped hollow carbon nanotubes catalyze the bromine reaction through nitrogen doping, reducing the overpotential; the hollow structure adsorbs bromine species and uses charge action to inhibit bromine permeation, reducing self-discharge. On the negative electrode side, the boron-nitrogen co-doped carbon uses B-N zinc-loving sites to guide uniform and dense zinc deposition, inhibiting dendrite formation; and inhibits hydrogen evolution through charge regulation. Both methods synergistically improve the bromine barrier performance, reaction kinetics, and dendrite suppression ability of the carbon-plastic bipolar plate.
