Beschreibung
Zusammenfassung:	The invention discloses a composite electrode material with high electrochemical stability prepared from waste PVC, and is characterized by being prepared from the following raw materials in parts by weight: 2 to 3 parts of lithium cobaltate, 1 to 2 parts of polyvinylpyrrolidone, 2 to 3 parts of 3,4- ethylenedioxythiophene, 1 to 2 parts of polyvinylidene fluoride, 1 to 3 parts of vinyltriethoxysilane, 8 to 15 parts of distilled water, 1 to 2 parts of copper powder, 1 to 3 parts of hafnium diboride, and 100 to 130 pars of modified waste PVC-based active carbon. The active carbon prepared by use of waste PCV material has the advantages of large specific surface area, high conductive efficiency, simple preparation technology and the like, the added lithium cobaltate can suppress cell polarization, a heat effect is reduced, rate performance is improved, internal resistance of a cell can be reduced, consistency is improved, and a function of increasing a cycle life of the cell is realized.
