Abstract
The present application provides a method of preparing lithium-friendly colloid paint. The method comprises functionalizing a carbon nanotube material to obtain a plurality of carbon nanotubes with functional groups; dispersing the of carbon nanotube material with functional groups in a solution containing nitrogen molecules to from the dispersion liquid to obtain a carbon nanotube precursor; heat-treating the carbon nanotube precursors to obtain a plurality of nitrogen-doped carbon nanotubes; dispersing the plurality of nitrogen-doped carbon nanotubes in an organic solvent, and adding a dispersant obtain a nitrogen-doped carbon nanotube solution precursor; and providing a polymer material colloid and a lithium salt, and uniformly mixing the nitrogen-doped carbon nanotube solution precursor, the lithium salt and the polymer material colloid.
