The latest developments on functional separators for long-life and safe Li metal batteries have been summarized and discussed in this minireview, including mechanically strengthened separator fabrication, functional separator construction towards regulated Li ion deposition, and flame-retardant separator design.
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 performance of the battery is significantly impacted by the features and functions of the separator. In addition to the appropriate preparation technique, the choice of materials, whether the raw material for preparing the separators or the modification material, is even more crucial for the performance of functionalized separators.
Although many batteries with modified separators were reported to have high performance, it is a challenge to improve the performance of the batteries while maintaining a long-life cycle, high sulfur loading, or low electrolyte/sulfur (E/S) ratio.
Mechanical properties of the separator play a crucial role in the long-cycle stability and safety of batteries, which are connected with the properties of the material and the fabrication process. Normally the tensile strength, elongation at break and puncture strength of the separator are researched.
