A method for preparing a carbon fluoride/fluorinated metal composite material comprises the steps of: carbonizing at least one of the group consisting of copper-based, iron-based, cobalt-based, nickel-based, and manganese-based metal organic framework materials at a high temperature in an inert gas atmosphere, then cooling the organic framework material to room temperature to obtain a composite material precursor; drying the composite material precursor in a reaction vessel, then introducing a mixed gas composed of a fluorine gas and a nitrogen gas, performing a fluorination under a heating condition, and performing vacuum drying to obtain the carbon fluoride/fluorinated metal composite material as a final product. The method is low in raw material cost, easy to operate and liable to industrial production. The fluorinated metal and carbon fluoride composite materials are prepared by an in-situ method. The two materials have high recombination degree, and the composite material has richinner pores and high spe
