【 摘 要 】

tsThe synergistic “anchor-capture” mechanism of polar groups on Zn stripping/plating process is firstly proposed.The amino group firmly anchors on Zn surface and the carboxyl group strongly captures Zn2+, constructing a robust anode–electrolyte interface and inducing uniform Zn deposition.The ultra-stable cycle lifespan of Zn–Zn symmetric cell (over 2800 h) and high utilization rate of Zn anode (the depth of discharge up to 68% for 200 h) are achieved under the proposal of synergistic “anchor-capture.”
