1. A method for preparing carbon nanotube sodiophilic metal anode-free sodium metal battery electrode material, comprising:
modifying carbon nanotubes by dielectric barrier plasma equipment to obtain modified carbon nanotubes;
mixing and stirring the modified carbon nanotubes with a sodiophilic metal salt to obtain a precursor slurry;
drying the precursor slurry, placing the precursor slurry in a tube furnace after drying, and heating to react under a reducing gas, thereby obtaining a carbon nanotube sodiophilic metal anode-free sodium metal battery electrode material.
