Abstract

The invention discloses a mononuclear fluorine-substituted bimetal phthalocyanine complex / activated carbon lithium thionyl chloride battery catalytic material and a preparation method thereof. 4-fluorophthalic anhydride, cobalt chloride hexahydrate, copper chloride dehydrate, pitch coke activated carbon and urea which are as raw materials and ammonium molybdate which is used as a catalyst are uniformly ground in a glass mortar and then are placed in a muffle furnace for solid phase sintering to obtain a target product. The method has a simple preparation process, low cost, easily controlled preparation conditions, a short synthesis cycle and uniform compositions. The composite material prepared by the method can increase the ion activation surface area and accelerate electron transport. The high specific surface area of the pitch coke activated carbon, the certain catalytic properties of a pore structure and a microcrystalline structure and the mutual competition and synergistic effects of the bimetal affect the catalytic performance of the composite material together, improve the electrochemical performance of the lithium thionyl chloride electrode material, and reduce contact resistance between interfaces.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a mononuclear fluorine-substituted bimetallic phthalocyanine complex / activated carbon lithium thionyl chloride battery catalytic material and a preparation method thereof. Background technique [0002] The use of energy marks the development and progress of human civilization, which has also become an indispensable material condition for social development. According to relevant reports, 70% of the energy consumption in the world today comes from fossil fuels and some non-renewable resources. However, unrestrained exploitation and use have caused an energy crisis. At the same time, the gases harmful to the environment produced during the combustion of fossil fuels have seriously affected human development. People have paid more and more attention to the idea of ​​changing the unreasonable energy structure and seeking an energy path suitable for the sustainable developm...
