The excellent cycling performances of Zn anode by using zincophilic and hydrophobic PFA-COOH-CNT artificial SEI film

Caption

The 3D porous PFA-COOH-CNT artificial SEI membrane promoted the uniform deposition of zinc ions and hindered the direct contact between water and electrolyte through its zincophilic and hydrophobic properties, thus inhibiting the growth of zinc dendrites and the occurrence of hydrogen evolution reaction. At the current density of 1 mA‧cm−2, 1 mAh‧cm−2, the ultra-long cycle of 2200 h is achieved.
