Abstract
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.
