Organic negative electrode material based on reactive dye as well as preparation method and application of organic negative electrode material

The invention discloses an organic negative electrode material based on reactive dye and a preparation method and application thereof, alizarin and alizarin red are used as battery negative electrode materials, the organic negative electrode material is used as one of industrial dyes, the selection range of aqueous battery negative electrode materials is widened, meanwhile, a PBI diaphragm is used as a diaphragm of a battery, and the service life of the battery is prolonged. The influence caused by dye dissolution is also solved, the comprehensive performance of the battery is improved by optimizing the type and concentration of the electrolyte, in addition, the aqueous battery formed by the alizarin organic negative electrode and the commercialized sintered nickel positive electrode is wide in raw material source and low in price, and the problem that an existing aqueous battery is high in price can be effectively solved. 本发明公开了一种基于活性染料的有机负极材料及其制备方法和应用，本发明以茜素和茜素红作为电池负极材料，其作为工业染料的一种，提高了水系电池负极材料的选择范围，同时使用PBI隔膜
