A CATHODE OF A LITHIUM-AIR BATTERY, A LITHIUM-AIR BATTERY INCLUDING THE SAME, AND FABRICATION METHOD OF THE CATHODE OF THE LITHIUM-AIR BATTERY

摘要

A method of manufacturing a positive electrode for a lithium-air battery includes providing a carbon sheet and forming a coating layer including a solid electrolyte on at least one surface of the carbon sheet. The forming of the coating layer includes providing a solid electrolyte solution on at least one surface of the carbon sheet, drying the solid electrolyte solution, and heat-treating the dried solid electrolyte solution. The solid electrolyte is Li 2 SP 2 S 5 , Li 3.25 Ge 0 .25 P 0. 75 S 4, Li 10 GeP 2 S 12, LiNbO 3, Li 3 PO 4, Li 7 La 3 Zr 2 O 12, Li 3 BO 3 , and Li 0.5 La 0.5 TiO 3 at least one of includes
