Abstract
The invention relates to a zinc-manganese-oxygen positive electrode material and its preparation method and application. The positive electrode material comprises: a core, the core is zinc-manganese oxide particles; a shell, the shell is coated on the outer surface of the core, the The core is non-covalently bonded to the shell, which is a conductive polymer. The cycle stability of the zinc-manganese-oxygen cathode material is high, and the capacity fading rate of a battery comprising the zinc-manganese-oxygen cathode material is low.
Description
Zinc manganese oxide cathode material and preparation method and application thereof technical field The present invention relates to the field of energy materials, specifically, the present invention relates to a zinc-manganese-oxygen positive electrode material and a preparation method thereof and application. Background technique Zinc is rich in resources, low in cost, high in capacity and environmentally friendly, and is considered to be the most promising negative energy source for new energy devices. one of the most important materials. Therefore, aqueous zinc-ion batteries (ZIBs, with zinc as the negative electrode) have been considered as the next generation energy storage technology in Africa. Often promising alternatives. The development of high-performance cathode materials has become the key to the development of zinc-ion batteries. However, currently the The research on ZIB cathode materials is still in its infancy and is quite challenging. Among the...
