摘要：In aqueous zinc ion batteries, it is crucial to improve the ionic and electronic conductivity of the artificial protective layer to address the challenges of slow ion transport kinetics, Zn dendrite growth, and high interfacial charge transfer resistance. Herein, we design a fluorine-rich poly(3,4-ethylenedioxythiophene) (F-PEDOT) interfacial layer with enhanced electronic and ionic conductivity for highly stable Zn anodes. The PEDOT network serves as a fast electron transport channel to accelerate interfacial charge transfer. In addition, the -F group exhibits a strong affinity with Zn2+, leading to the accelerated Zn2+ transport, uniform diffusion and deposition of Zn2+ with inhibited dendrite growth. Therefore, F-PEDOT@Zn symmetrical batteries operate stably for more than 350 h at an ultra-high current density of 30 mA cm-2 and an areal capacity of 15 mAh cm- 2. Moreover, F-PEDOT@Zn//V2O5@Mxene full battery delivers capacity retention of 98.6 % after 1000 cycles at 10 A g- 1. This work provides an effective strategy for constructing a strong and effective Zn anode protection layer.
