NOVELTY - The method involves mixing graphene straight sheets, aluminum powder, conductive agent, carbon nanotubes, styrene butadiene rubber, sodium carboxymethyl cellulose and copper foil in a certain proportion. The mixture is added to the mixer, and the titanium sulfate is added to the mixer while stirring, so that the raw materials are evenly stirred. The sintered product is cooled down, and the cooled materials are screened to separate the insufficiently sintered raw materials in the materials and retain the fully sintered raw materials. The raw materials and the binder are mixed according to a certain ratio to form an intermediate material layer. A metal lithium layer of a certain thickness is uniformly vaporized on the intermediate material layer. The intermediate material layer is coated on the current collector, and the tabs are connected to the current collector to complete the preparation of the negative electrode of the lithium battery. USE - Preparation method of lithium battery negative electrode material applied to mobile phone, notebook computer, camera, digital camera and other civil and military field. ADVANTAGE - The preparation method is simple to operate, the raw materials are more uniformly dispersed, and the conductive effect is improved. The vaporized lithium metal can inhibit the generation of lithium branch crystals during the charging and discharging process of the battery, and improve the safety of the battery.
