| Abstract:As an essential component of batteries， separators physically isolate the anode and cathode to prevent short circuits. Their microstructural properties critically influence battery cycling efficiency and capacity retention. With the rapid adoption of new energy vehicles in recent years， the demand for high-performance battery separators has intensified. Conventional polyolefin-based separators face limitations such as poor thermal resistance causing shrinkage， inadequate electrolyte wettability， and other drawbacks that hinder their application in next-generation high-efficiency battery systems. Consequently， modification of traditional separators or adoption of novel separator materials has become imperative. This paper systematically summarized recent global advances in both modified conventional separators and emerging separator materials. It further analyzed existing technological bottlenecks， challenges in developing high-performance separators， and future research directions. This work provided valuable insights for advancing separator technology and enhancing overall battery charge-discharge performance. |
