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 metal 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.
