Abstract: A method for preparing a carbon nanotube sodiophilic metal anode-free sodium metal battery electrode material is provided, and the method includes the following steps: the carbon nanotubes are modified by a dielectric barrier plasma device; the modified carbon nanotubes are mixed and stirred with a sodiophilic metal salt to obtain a precursor slurry; the precursor slurry is dried, placed in a tube furnace after drying, and heated by introducing a reducing gas to react, thereby obtaining a carbon nanotube sodiophilic metal anode-free sodium metal battery electrode material. The electrode material prepared by the method has a stable structure, excellent electrical conductivity, and excellent sodium affinity, and can be applied to anode-free sodium metal battery electrode materials. The entire preparation process is controllable, the synthesis cycle is short, and the operation is simple.
