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 modern state of art and the challenges in the field of Li–air batteries are considered. Although their implementation holds the greatest promise in a number of applications ranging from portable electronics to electric vehicles, there are also impressive challenges in development of cathode materials and electrolyte systems of these batteries.
In addition, the complicated component of air (e.g., H 2 O, CO 2) markedly hinders the transformation from Li–O 2 to Li–air batteries, which not only changes the reaction mechanism, discharge products, and energy efficiency at the cathode side but also leads to the corrosion of Li metal and safety issues at the anode side.
Severe problems in non-aqueous systems, such as decomposition of the electrolyte, clogging of the porous air cathode by the insoluble discharge product of Li 2 O 2, and contamination by water from the air, are not appreciable in the aqueous lithium–air system.
Zhang and co-workers investigated the influence of carbon loading on the performance of Li-air batteries and maximized the area-specific capacity of KB-based air cathodes with a carbon loading of 15.1 mg cm −2. 26 They suggested that the uniformity of pore sizes was crucial, and larger mesopore volumes would lead to higher capacity. 2.
In cells using cathodes made from Super P and Ketjen Black, for example, conclusions have been made linking to discharge being stopped in Li-air batteries due to the loss of surface area near the air inlet. As the battery is used, Lithium peroxide deposits along the walls of pores, gradually sealing them.

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. Indeed, the theoretical specific energy of a non-aqueous Li–air battery, in the charged state with Li2O2 product and excluding the oxygen mass, is ~40.1 MJ/kg = 11.14 k…

Lithium–air battery
Li–air batteries recaptured scientific interest late in the first decade of the 2000s due to advances in materials science. Although the idea of a lithium–air battery was around long before 1996,[12][13][14][15] the risk-to-benefit ratio was perceived as too high to pursue. Indeed, both the negative (lithium metal) and the positive (air or oxygen electrodes) are the reasons why ...
