“…Metal-air batteries are considered to be one of the most promising power sources for portable power supplies, emergency power supplies, consumer applications, etc. [1][2][3] Among them, the magnesium-air (Mg-air) battery is undoubtedly excellent with metal Mg as the anode, possessing many natural advantages. Mg has a lower electrode potential (−2.37 V vs. SHE) than Zn and Al metals, a higher theoretical volume capacity of 3866 mA h cm −3 , a low density of 1.74 g cm −3 , and a high crustal abundance (i.e., approximately 2.1%, about a thousand times that of Zn metal).…”

“…have also been used in metal-air batteries with gratifying results, which satised the different needs of cathode and anode through electrolyte decoupling. 3,7,29,30 Inspired by these exciting achievements of the solid electrolyte on metal-based batteries, herein we prepared a novel sodium alginate (SA)/NaCl solid electrolyte and designed an acetic acid-SA/NaCl solid anolyte biphasic electrolytes system for Mg-air batteries. Due to the excellent inhibitory effect of the SA/NaCl solid electrolyte on passivation and hydrogen evolution corrosion, the anode utilization efficiency increased from 9.6% (10 wt% NaCl aqueous solution electrolyte) to 61.5% at 0.1 mA cm −2 .…”

With the rapid development of portable electronics and electric road vehicles, high-energy-density batteries have been becoming front-burner issues. Traditionally, homogeneous electrolyte cannot simultaneously meet diametrically opposed demands of high-potential cathode and low-potential anode, which are essential for high-voltage batteries. Meanwhile, homogeneous electrolyte is difficult to achieve bi- or multi-functions to meet different requirements of electrodes. In comparison, the asymmetric electrolyte with bi- or multi-layer disparate components can satisfy distinct requirements by playing different roles of each electrolyte layer and meanwhile compensates weakness of individual electrolyte. Consequently, the asymmetric electrolyte can not only suppress by-product sedimentation and continuous electrolyte decomposition at the anode while preserving active substances at the cathode for high-voltage batteries with long cyclic lifespan. In this review, we comprehensively divide asymmetric electrolytes into three categories: decoupled liquid-state electrolytes, bi-phase solid/liquid electrolytes and decoupled asymmetric solid-state electrolytes. The design principles, reaction mechanism and mutual compatibility are also studied, respectively. Finally, we provide a comprehensive vision for the simplification of structure to reduce costs and increase device energy density, and the optimization of solvation structure at anolyte/catholyte interface to realize fast ion transport kinetics.
