2.3. Rechargeable solid-state and molten salt lithium–air batteries The serious problems of lithium–air batteries with liquid electrolytes are leakage and evaporation of the electrolyte over long operation period of more than 10 years for EVs and stationary use under open air.
The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow. Pairing lithium and ambient oxygen can theoretically lead to electrochemical cells with the highest possible specific energy.
The main side products in non-aqueous and solid-state lithium-air batteries are lithium carbonate (Li 2 CO 3) and lithium hydroxide (LiOH) come from carbon dioxide and water in ambient air. The combination of proper catalysts may realize the operation of lithium-air batteries in ambient air.
Using lithium, the lightest metal, and ubiquitous O 2 in the air as active materials, lithium-air (Li-air) batteries promise up to 5-fold higher specific energy than current Li-ion batteries at a lower cost.
The overpotentials for the ORR and OER in aqueous lithium–air batteries are considerably lower than those in the non-aqueous lithium–air batteries. Li and Manthiram reported that a Pt/C and IrO 2 composite air electrode reduced the overpotential for the OER in an acid catholyte.
