Given their high safety, environmental friendliness and low cost, aqueous zinc-ion batteries (AZIBs) have the potential for high-performance energy storage. However, issues with the structural stability and electrochemical kinetics during discharge/charge limit the development of AZIBs. In this study, vanadium oxide electrodes with organic molecular intercalation were designed based on intercalating 11 kinds of charged organic carboxylic acid ligands between 2D layers to regulate the interlayer spacing. The negatively charged carboxylic acid group can neutralize Zn2+, reduce electrostatic repulsion and enhance electrochemical kinetics. The intercalated organic molecules increased the interlayer spacing. Among them, the 0.028EDTA · 0.28NH4+ · V2O5 · 0.069H2O was employed as the cathode with a high specific capacity (464.6 mAh g-1 at 0.5 A g-1) and excellent rate performance (324.4 mAh g-1 at 10 A g-1). Even at a current density of 20 A g-1, the specific capacity after 2000 charge/discharge cycles was 215.2 mAh g-1 (capacity retention of 78%). The results of this study demonstrate that modulation of the electrostatic repulsion and interlayer spacing through the intercalation of organic ligands can enhance the properties of vanadium-based materials.
锌离子水电池(AZIBs)具有安全性高、环保和成本低的特点,有望成为高性能的储能电池。然而,放电/充电过程中的结构稳定性和电化学动力学问题限制了 AZIB 的发展。本研究基于在二维层之间插层 11 种带电的有机羧酸配体来调节层间距,设计出了具有有机分子插层的氧化钒电极。带负电荷的羧酸基团可以中和 Zn2+,减少静电排斥,增强电化学动力学。插层有机分子增加了层间距。其中,0.028EDTA - 0.28NH4 + - V2O5 - 0.069H2O 被用作阴极,具有较高的比容量(0.5 A g-1 时为 464.6 mAh g-1)和优异的速率性能(10 A g-1 时为 324.4 mAh g-1)。即使在电流密度为 20 A g-1 时,经过 2000 次充放电循环后,比容量仍为 215.2 mAh g-1(容量保持率为 78%)。这项研究的结果表明,通过插层有机配体来调节静电排斥力和层间距,可以提高钒基材料的性能。

Spin chemistry has emerged as an interdisciplinary field that focuses on electron spins in molecules and related applications in physics, chemistry, biology, materials science and information science. It will play a crucial role in technological innovations. The chemistry of spins is deeply related to the essence of chemical bonds, chemical catalysis, enzyme catalysis, optical and electromagnetic properties, quantum computation and quantum precision measurements. The related research is intersectional, cutting-edge and has a wide range of application prospects. National Science Review (NSR) recently interviewed Prof. Song Gao to discuss spin chemistry. Prof. Gao is a renowned inorganic chemist and an academician of Chinese Academy of Sciences. He is the president of Sun Yat-sen University and the founder of the Spin-X Institute of South China University of Technology. He is recognized as a leader in coordination chemistry and molecular magnetism, and has strong academic influence. Since 2008, he has served on the International Advisory Committee of International Conference on Molecule-Based Magnets, and organized and chaired its 2010 conference. Prof. Gao's primary research topics include molecular nanomagnets; the relationship between geometric structures, electronic structures and magnetism of molecules; and the spin states and reactivity of molecules.
