摘要
金属锌阳极的实际应用受到枝晶生长和氢进化反应(HER)的限制,尤其是在高电流密度条件下。之前的研究表明,构建 Zn(002) 纹理可有效抑制枝晶生长和氢化反应。然而,商用金属锌的表面晶粒分布仍然模糊不清。在此,我们展示了一种简单的机械研磨方法来构建 (002) 纹理的锌金属阳极。研磨后,商用金属锌的 (002) 相对纹理系数从 10.58 增加到 42.28,表明 (002) 平面暴露显著增加。制备的(002)纹理锌阳极临界电流密度高达 141 mA cm-2,在 50 mA cm-2 和 1 mAh cm-2 的条件下可稳定循环超过 1500 次。得益于这种(002)质地锌阳极的稳定性和快速动力学特性,锌离子电容器的功率密度达到 8500 W kg-1,长循环次数超过 10 000 次,库仑效率(CE)超过 99.9%。这项研究为无枝晶和抑制 HER 的锌金属阳极提供了基础性和实用性见解,并为其他金属电池提供了启发性指导。
Mechanical Grinding Formation of Highly Reversible (002)-Textured Zinc Metal Anodes
The practical applications of zinc metal anode are restricted by detrimental dendrite growth and hydrogen evolution reaction (HER), especially at high current densities. Previous works have demonstrated that constructing Zn(002) texture could effectively suppress dendrite growth and HER. However, the surface grain distribution of commercial zinc metal remains indistinct. Herein, a simple mechanical grinding approach is demonstrated to construct (002)-textured zinc metal anodes. After grinding, the (002) relative texture coefficient of commercial zinc metal increases from 10.58 to 42.28, indicating a significant more (002) planes exposure. As prepared (002)-textured zinc anode exhibits a high critical current density of 141 mA cm−2 and stably cycles for over 1500 cycles at 50 mA cm−2 and 1 mAh cm−2. Benefiting from the stability and fast kinetics of this (002)-textured zinc anode, the zinc-ion capacitor achieves a power density of 8500 W kg−1 and long cycle over 10 000 cycles with Coulombic efficiency (CE) exceeding 99.9%. This work provides both fundamental and practical insights for dendrite-free and HER-suppressed zinc metal anodes and inspiring guidance for other metal batteries.
