Abstract: Evolution of Zn anode studies and progresses
Aqueous Zinc batteries (AZBs) have garnered significant attention as a candidate for large-scale energy storage. The values of the numbers have been largely enhanced while AZBs are still struggling with further practical applications, which is the reason this is worthy of deep analysis and study. With this aim, we explore the evolution of AZBs in recent years and the research trend shift, identifying the separator study might be the missing puzzle. We then revealed that separator thickness profoundly impacts volumetric and specific energy densities and have significant influence on battery lifespan. Accordingly, we propose the index of thickness ratio (Zn foil/separator) as a critical factor affecting the lifespan, providing a rational basis for future related studies. Our work underscores the importance of integrated design of both anode and separator to achieve high depth of discharge (DOD) and areal capacity, essential for advancing AZB commercialization.
