The present invention proposes a kind of preparation method of the negative electrode material of lithium-air battery, the negative electrode material is high-temperature calcination after graphene microchip and calcium oxide mixing and ball milling, then high-temperature process is mixed with lithium carbonate, then corona treatment is carried out after the melting of obtained dusty material being pressed into bulk material, carbonic acid lithium layer is covered on lithium metal surface and is made, negative electrode material provided by the invention, thermal stability with higher, and effectively contain the generation for having lacked side reaction, avoid corrosion and the inactivation of electrode material, improve the stability and safety of lithium-air battery system, it can promote the development and application of lithium-air battery. |
