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 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.
For the commercial application of LIBs and SIBs in the future, design a "smart separator" might be developed. The sensor is introduced into the separator to monitor changes in heat, pressure and gas during battery operation, and at the same time to achieve the purpose of reversible protection of the battery.
In addition, polyolefin separators, cellulose separators and glass fiber separators are reviewed and discussed. Finally, the industrialization process and future trends of sodium batteries are outlined. Energy underpins the success and development of human society.
The separator plays the pivotal role in normal LIBs and SIBs device and there is a close relationship between separator and battery safety , . The separator acts as a physical barrier to insulate cathode and anode from direct contact and accommodate electrolyte to facilitate ions shuttle inside the battery.
At present, researches on separators still focus on the improvement performance of the dendrite growth, ion transport, mechanical properties and wettability. Functional separators are also key to improving the electrochemical performance of batteries.
