Since both ORR and OER occur in the air electrode, it poses major technology challenges for lithium-air batteries. The ultimate goal is to achieve high capacity and power density, high round-trip efficiency, and a long cycling life. Reaching that goal depends on the material and the microstructure.
These undesired reactions consume lithium and result in a thick passivation layer on the lithium surface, increasing the lithium ion transport resistance and eventually leading to the performance decay and even the failure of the battery.
Meanwhile, a membrane that can suppress the evaporation of liquid electrolytes is needed for long-term operation of non-aqueous, aqueous, and hybrid lithium-air batteries. Metallic lithium is typically chosen as the anode material in most studies of lithium-air batteries, which is expected to achieve the highest capacity and energy.
In past lithium-air designs, the lithium in a lithium metal anode moves through a liquid electrolyte to combine with oxygen during the discharge, yielding lithium peroxide (Li 2 O 2) or superoxide (LiO 2) at the cathode. The lithium peroxide or superoxide is then broken back down into its lithium and oxygen components during the charge.
Fig. 1. Schematic configurations of lithium-air batteries. In non-aqueous lithium-air batteries, oxygen is reduced and forms solid Li 2 O 2 in the porous cathode. The capacity of this battery system is therefore mainly limited by the clog of the solid product and/or passivation of active surfaces at the porous cathode .
In the discharging process, lithium metal is oxidized to Li + and then migrates to the air cathode. In the meantime, oxygen accepts electrons from the external circuit and combines with Li + to form discharge products on the air cathode. When charging the batteries, the electrochemical processes are reversed.
