LIQUID METAL-IN-CARBON NANOTUBE LITHIUM AIR BATTERY POSITIVE ELECTRODE AND PREPARATION METHOD THEREFOR

Disclosed in the present invention are a liquid metal-in-carbon nanotube lithium air battery positive electrode and a preparation method therefor. Liquid metal is one selected from gallium-tin liquid metal and gallium-indium liquid metal, and the size distribution of the liquid metal ranges from 100 nm to 800 nm. The compounding mode of the liquid metal and a carbon nanotube is one selected from a blending method and a dropwise adding method, and the mass ratio of the liquid metal to the carbon nanotube is 1:1 to 10:1. The liquid metal-in-carbon nanotube lithium air battery positive electrode prepared by the present invention has good full discharge capacity, rate capability, cycling stability, and passivation prevention capability.
