The battery separator is one of the most essential components that highly affect the electrochemical stability and performance in lithium-ion batteries. In order to keep up with a nationwide trend and needs in the battery society, the role of battery separators starts to change from passive to active.
Current commercial separators lack the ability to efficiently regulate polysulfide shuttling and are prone to thermal runaway at high temperatures. Recent studies have shown that multifunctional separators can boost the electrochemical performance and safety of Li–S batteries.
Li–S batteries equipped with the HKUST-1@GO composite separator preserve a discharge capacity of 855 mAh g −1 even after 1500 cycles, demonstrating exceptional cycling stability. Bai et al. similarly employed a Zn-based MOF (Zn-HKUST-1) to obtained a composite separator with GO through the same process (Figure 10b).
Separators woven purely from inorganic materials, especially one-dimensional inorganic materials, possess extremely high thermal stability and structural retention capabilities. The next focus is on how to improve the mechanical properties of inorganic separators to make them more suitable for battery processing.
Lithium-ion batteries employ three different types of separators that include: (1) microporous membranes; (2) composite membranes, and (3) polymer blends. Separators can come in single-layer or multilayer configurations. Multilayered configurations are mechanically and thermally more robust and stable than single-layered configurations.
Multifunctional separators offer new possibilities to the incorporation of ceramics into Li-ion battery separators. SiO 2 chemically grafted on a PE separator improves the adhesion strength, thermal stability (<5% shrinkage at 120 °C for 30 min), and electrolyte wettability as compared with the physical SiO 2 coating on a PE separator .
