An ion-selective separator suppresses polysulfides shuttle
Obviously, the Li–S battery with the ZSM/C/Nafion@PP separator has the highest capacity retention rate of 77.18% from 0.1 to 2 °C compared to the PP separator (38.33%) and C@PP separator (50.58%). It is well known that the polysulfide shuttle will lead to the deposition of Li 2 S/Li 2 S 2 on surface of the Li metal anode, causing Li anode degradation [ 51, 52 ].
