▎ 摘　　要

NOVELTY - The electrode has a dual-side electrode structure provided with a nano-graphite layer and a nano graphene-containing layer. The nano graphene-containing layer is adhered with an oxygen selective membrane i.e. PTFE film. Adhesive is selected from polyethylene, polypropylene or polyvinylidene fluoride. A metal elementary substance is selected from material group consisting of platinum (Pt), silver (Ag), gold (Au), cobalt (Co), zinc (Zn), chromium (Cr), palladium (Pd), rhodium (Rh), cadmium (Cd), niobium(Nb), molybdenum (Mo), ruthenium (Ru) and nickel (Ni). USE - Air electrode for a high-energy density lithium battery. ADVANTAGE - The electrode has high electrolyte conductivity, low volatility and better chemical stability, and improves safety performance of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an air electrode preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an air electrode.
