Summary:

The present invention belongs to the field of lithium battery, and more specifically, relates to a metal lithium anode material and a preparation method thereof. The 

lithium metal anode provided by the present invention is formed by coating an organic polymer material with good lithium ion transmission on the surface of lithium me

tal to form a polymer protective film, and the organic polymer is a heteroatom-doped polyacrylonitrile polymer. The method is easy to operate, low cost, and suitable 

for large-scale production. The lithium metal anode prepared by the present invention can greatly improve the cycle performance and energy density of the lithium metal

secondary battery.
