Advanced Energy Materials, Год журнала: 2024, Номер unknown

Опубликована: Окт. 7, 2024

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 HER. However, the surface grain distribution commercial remains indistinct. Herein, a simple mechanical grinding approach is to construct (002)‐textured anodes. After grinding, (002) relative coefficient increases from 10.58 42.28, indicating significant more planes exposure. As prepared exhibits critical density 141 mA cm −2 stably cycles for over 1500 50 1 mAh . Benefiting stability fast kinetics this anode, zinc‐ion capacitor achieves power 8500 W kg −1 long cycle 10 000 with Coulombic efficiency (CE) exceeding 99.9%. This work provides both fundamental insights dendrite‐free HER‐suppressed anodes inspiring guidance other batteries.

Electrode-electrolyte interface plays a crucial role in determining the stability and behavior of electrochemical electrodes. Although X-ray photoelectron spectroscopy has been established as powerful analytical technique for chemistry, necessity ultrahigh vacuum remains significant obstacle to directly detecting dynamic interfacial evolution, particularly aqueous environments. Here, we employ tender-energy ambient pressure (AP-XPS) bridge gap between near-atmospheric pressure, enabling an in-depth investigation molecule-crowded evolution Zn metal anode. The results demonstrate that persistent presence additive molecules effectively inhibits direct contact reactive H2O, while also facilitating uniform deposition. In situ optical microscopy observations synchrotron radiation diffraction further verified dense deposition, attributed lateral growth induced by (002) crystal facet evolution. As proof its effectiveness, batteries incorporating Zn//Zn, Zn//Cu, full cell with significantly improved reversibility. This finding opens up new avenues exploration chemistry at molecule level, offering insights into design highly stable anodes ion practical applications.
