Research Progress on Separator Modification Materials for Lithium-sulfur Batteries
Lithium-sulfur batteries have high theoretical specific capacity and energy density,and the economy and environmental friendliness of the battery itself are also prominent,so they have become a hot spot in the field of energy batteries in recent years.However,the shuttle effect of polysulfides in the battery will seriously affect the cycling performance and coulombic efficiency of the battery,hindering the commercialization of lithium-sulfur batteries.The results show that the shuttle effect can be limited to a certain extent by modifying the separator inside the lithium-sulfur battery.At present,the key modified materials are roughly divided into metals,carbons and polymers.
