Abstract
Aqueous zinc metal batteries (AZMBs) represent one of the most promising next-generation energy storage devices in terms of competitiveness. However, the commercialization of AZMBs has been significantly impeded by the occurrence of random dendrite growth and inevitable parasitic reactions on Zn metal anodes. In order to address this issue, we propose a solution wherein the surface of Zn foil is retouched through a replacement reaction with zincophilic and low-active Cu particles (designated as CuRZn). The CuRZn electrode exhibits exceptional corrosion resistance and enables stable Zn plating/stripping via alloying/dealloying processes. Consequently, the CuRZn||CuRZn symmetric battery exhibits stable operation for over 3200 h under 1 or 5 mA cm−2 and 1 mA h cm−2, and the CuRZn||Cu asymmetric battery achieves an excellent coulombic efficiency of 99.86 % under 2 mA cm−2 and 1 mA h cm−2 for over 2300 cycles. When coupled to an ammonium vanadate (NVO) cathode, the performance of the CuRZn||NVO full battery, which has a larger capacity (183.4 mA h g−1) than that of the bare Zn||NVO full battery (94.8 mA h g−1) at 2 A g−1, greatly improves after 1000 cycles. This study provides a simple and efficient surface retouching strategy for Zn metal anodes to achieve high-performance AZMBs.
锌金属水电池(AZMB)是下一代能源存储设备中最具竞争力的产品之一。然而,由于锌金属阳极上出现随机枝晶生长和不可避免的寄生反应,AZMB 的商业化受到了严重阻碍。为了解决这个问题,我们提出了一种解决方案,即通过亲锌、低活性铜颗粒(称为 CuRZn)的置换反应来修饰锌箔表面。CuRZn 电极具有优异的耐腐蚀性,可通过合金化/合金化工艺实现稳定的锌电镀/剥离。因此,CuRZn||CuRZn对称电池在1或5 mA cm-2和1 mA h cm-2条件下可稳定工作3200小时以上,而CuRZn||Cu不对称电池在2 mA cm-2和1 mA h cm-2条件下可达到99.86%的出色库仑效率,循环次数超过2300次。当与钒酸铵(NVO)正极耦合时,CuRZn||NVO全电池在2 A g-1下的容量(183.4 mA h g-1)比裸Zn||NVO全电池的容量(94.8 mA h g-1)大,并且在1000次循环后性能大大提高。这项研究为锌金属阳极实现高性能 AZMB 提供了一种简单高效的表面修饰策略。
