Abstract
flux regulation, dendrite suppression, and long-term cycling stability. Additionally, emerging separator materials such as covalent organic frameworks (COFs), metal-organic frameworks (MOFs), and inorganic-organic hybrid separators are highlighted for their potential in optimizing battery performance. By elucidating the underlying mechanisms governing separator modifications, this review provides theoretical insights and design principles for the development of next-generation AZB separators. Finally, we discuss future research directions, focusing on separator thinness, enhanced ion selectivity, interface stability, corrosion resistance, and scalable manufacturing to accelerate the commercialization of high-performance AZBs.
