Nevertheless, the limited specific capacity of PBAs constrains their broader application in aqueous zinc-based batteries. To date, several categories of electrodes have been employed as cathodes for aqueous zinc-based batteries, such as Prussian blue analogs and manganese-based oxides. "Among the various components of the battery, the cathode material plays a pivotal role in determining the electrochemical characteristics of aqueous zinc-based batteries. However, achieving satisfactory performance in practical applications still necessitates further endeavors," stated Bai.
"Aqueous zinc-based batteries have garnered significant attention from researchers due to the favorable redox potential and the excellent specific capacity of zinc metal. Nevertheless, the limited availability of lithium and concerns regarding the safety of organic electrolytes underscore the necessity of an ongoing quest for alternatives better suited to stationary energy storage."īai explained that aqueous secondary batteries have attracted attention as the prospective and viable candidates for grid-level energy storage because of the safe aqueous electrolytes in recent years. "While commercial lithium-ion batteries have witnessed widespread adoption in transportation and various flexible devices over the last three decades, their potential as energy storage sources is on the rise. "Aqueous secondary batteries hold substantial promise for stationary energy storage," notes Professor Ying Bai, affiliated with the School of Materials Science and Engineering at Beijing Institute of Technology.
