Title:
F-DOPED CARBON AIR ELECTRODE AND METHOD FOR MANUFACTURING LITHIUM-AIR BATTERY USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/116913
Kind Code:
A2
Abstract:
The present invention comprises: a step for manufacturing a cell using carbon paper as a cathode material, lithium metal as an anode, a separator therebetween, and an electrolyte containing a LiTFSI salt; and an F-doping step for doping the carbon paper with fluorine using a reduction reaction of LiTFSI, which is generated during discharging, in an inert atmosphere. According to the above technical feature, by generating a transfer path of oxygen ions on the surface of carbon through F-doping using an electrochemical reduction method and providing an additionally generated carboxyl group as a Li2O2 -producing site, there is an effect of manufacturing of a high-output and high-capacity lithium-air battery in which F-doped P50 exhibits a capacity per area of 30,000 µAh/cm2 or more, and Sp exhibits a capacity per weight of 200,000 mAh/g.
