Abstract

Zinc metal, a promising anode material, suffers from unpredictable side reactions and dendrite growth. These problems reduce its cycle performance and coulombic efficiency. To solve them, this study uses a bifunctional additive, sodium 1,2-dihydroxyanthraquinone-3-sulfonate (ARS). ARS modifies the solvation structure and forms a micro–hydrophobic interface. As a result, the Zn anode shows good reversibility. The Zn//Zn symmetrical battery can cycle for over 4000 h at 1 mA cm⁻². The Zn//Cu half–cell can cycle 4000 times at 4 mA cm⁻². The V₁₀O₂₄·12H₂O//Zn full cell also shows high capacity retention after 2500 cycles. This work offers a way to choose low–cost additives for large–scale ZIB deployment.

微量磺酸添加剂对高可逆锌阳极中Zn2+ SEI输运和脱溶的调节。

锌金属是一种很有前途的阳极材料，但其副反应和枝晶生长难以预测。这些问题降低了循环性能和库仑效率。为了解决这些问题，本研究使用了一种双功能添加剂，1,2-二羟基蒽醌-3-磺酸钠（ARS）。ARS改变了溶剂化结构，形成了微疏水界面。结果表明，锌阳极具有良好的可逆性。锌/锌对称电池在1ma cm−2下可循环4000 h以上。锌/铜半电池在4 mA cm−2下可循环4000次。V10O24·12H2O//Zn全电池在2500次循环后也显示出较高的容量保持率。这项工作为大规模使用ZIB提供了一种选择低成本添加剂的方法。
