Induced Anionic Functional Group Orientation-Assisted Stable Electrode-Electrolyte Interphases for Highly Reversible Zinc Anodes.

ABSTRACT: Dendrite growth and other side-reaction problems of zinc anodes in aqueous zinc-ion batteries heavily affect their cycling lifespan and Coulombic efficiency, which can be effectively alleviated by the application of polymer-based functional protection layer on the anode. However, the utilization rate of functional groups is difficult to improve without destroying the polymer chain. Here, a simple and well-established strategy is proposed by controlling the orientation of functional groups (─SO₃H) to assist the optimization of zinc anodes. Depending on the electrostatic effect, the surface-enriched ─SO₃H groups increase the ionic conductivity and homogenize the Zn²⁺ flux while inhibiting anionic permeation. This approach avoids the destruction of the polymer
