Chromium oxide/carbon fluoride/high-conductivity substance composite material for lithium primary battery

The invention belongs to the technical field of electrode material manufacturing, and particularly relates to a chromium oxide/carbon fluoride/high-conductivity substance composite material for a lithium primary battery. the electrode material is prepared by taking chromium trioxide as a reaction raw material and carbon fluoride and a high-conductivity substance premix as a doping material, and sequentially carrying out ball milling and oxygen introduction sintering on the reaction raw material and the doping material; AND carbon fluoride and a high-conductivity substance are selected as doping materials, chromium trioxide is taken as a raw material for preparing chromium oxide, and the doping materials are introduced in the whole process of forming the chromium oxide, so that the carbon fluoride and the high-conductivity substance can be uniformly doped on the surface of the chromium oxide or embedded into the chromium oxide while CrO3 is subjected to liquefaction and decomposition reaction at high temperatu
