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.
The use of separators that are thinner than conventional separators (> 20 µm) would improve the energy densities and specific energies of lithium batteries. However, thinner separators increase the risk of internal short circuits from lithium dendrites formed in both lithium-ion and lithium metal batteries.
Finally, we present a summary and future outlook of MPM-based functional separators. Insights from this review show that MPM-based functional separators can significantly enhance the electrochemical performance and safety of batteries.
Separators in batteries have a great influence on their performance and safety, where both the properties of the separator and the separator–electrode interfaces affect ion diffusion. Microporous polyolefin membranes (MPM) with excellent properties are widely used as separators in commercial lithium batteries.
Thin separators can improve batteries’ energy densities but increase cell shortcircuit risks. Here, the authors report an improved thin metal-organic frameworks separator to improve the dendrite formation resistance and cycling stability of high-voltage lithium battery in carbonate electrolytes.
The major role of the battery separator is to physically isolate the anode from the cathode while allowing mobile Li-ions to transport back and forth . Unfortunately, two technical challenges associated with separator puncture and significant thermal shrinkage of polymer separators threaten the overall safety of batteries.
