Fluorinated graphene/graphite fluoride composite positive electrode material and preparation method thereof

The invention discloses a preparation method of a fluorinated graphene/graphite fluoride composite positive electrode material, which comprises the following steps: by taking three-dimensional graphene and graphite as raw materials, dispersing and mixing to prepare a three-dimensional graphene/graphite mixed carbon source, placing the three-dimensional graphene/graphite mixed carbon source in a high-pressure and high-temperature container, and then introducing fluorine mixed gas into the high-pressure and high-temperature container for high-temperature fluorination to obtain the fluorinated graphene/graphite fluoride composite positive electrode material. According to the method disclosed by the invention, the conductivity of the positive electrode material is improved, the internal porosity of the material is improved, the power performance of the battery is improved, and meanwhile, the expansion of the lithium carbon fluoride battery in the discharging process is inhibited. 本发明公开了一种氟化石墨烯/氟化石墨复合正极材料的制备方法，以三维
