Abstract:Lithium air batteries have high energy density and low reduction potential. They are a green energy storage battery needed by modern society and have a wide range of applications. Because the traditional organic electrolytic has problems such as combustible, decomposition, the formation of lithium dendrites and the formation of a passivation layer that hinders the diffusion of O2, solid electrolytes need to be developed to improve the performance of lithium air batteries. This article first introduces the construction and working mechanism of lithium air batteries, and then summarizes the regulation strategy of the classic all-solid lithium air battery (ASSLAB), including the positive control strategy and electrolyte control strategy. At the same time, it summarizes the integrated design strategy of positive/electrolyte. Finally, it looks forward to the development direction of solid electrolyte, interface modification (i.e., the improvement of electrolyte and electrode interface resistance) and the optimization of air cathode design of lithium air batteries.
