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.
In alkaline batteries, the separators used are either regenerated cellulose or microporous polymer films. Lithium batteries with organic electrolytes mostly use microporous films. The type of separator can be divided into the following groups: There are a number of things that can cause an internal short circuit within a battery cell.
It is crucial to obtain an in-depth understanding of the design, preparation/ modification, and characterization of the separator because structural modifications of the separator can effectively modulate the ion diffusion and dendrite growth, thereby optimizing the electrochemical performance and high safety of the battery.
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.
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.
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.
