Two types of aqueous lithium-air batteries have been developed one contains an alkaline catholyte of LiOH, and the other contains an acid catholyte such as acetic acid, CH 3COOH (HAc). The aqueous lithium-air battery consists of a lithium anode, an interlayer non-aqueous electrolyte, a water-stable lithium-ion conducting solid electrolyte, an aqueous catholyte, and an air electrode. Of the options available, the aqueous lithium-air battery is particularly attractive for EVs because the battery has the potential for high energy and power densities, but no serious problems to be solved.
However, these batteries have serious problems to solve before their practical use as power sources in EVs, such as the elimination of water in the air in the non-aqueous lithium-air battery, dissolution of the reaction product into the electrolyte in the lithium-sulfur battery, and poor contact between the electrolyte and cathode active materials in the solid-state battery. The theoretical energy densities of these advanced batteries are several times higher than those of conventional lithium-ion batteries. Many types of advanced rechargeable batteries beyond lithium-ion batteries have been proposed and developed, such as non-aqueous lithium-air, aqueous lithium-air, lithium-sulfur, multivalent, and lithium solid-state batteries. The demand for higher energy power density rechargeable batteries for electric vehicle (EV) applications has increased. High energy density battery lithium-air battery aqueous battery, solid lithium-ion conductor acetic acid 1. The cell was successfully operated at 0.5 mA cm –2 and 0.2 MPa. In this study, we have studied the cell performance of a Li/interlayer electrolyte/NASICON-type solid lithium-ion conductor/acetic acid catholyte/air electrode cell at high pressure and room temperature under air. An aqueous lithium-air battery with an acetic acid catholyte has a high theoretical energy density of 1,478 Wh kg –1, and the reaction product is soluble in the catholyte.
