摘要

目前，用于锌离子电池（AZIBs）的过渡金属硫族化合物（TMDs）的开发一直受到其电导率和电化学性能差的困扰。本文采用一步球磨法，通过构建三维（3D）碳纳米管（CNTs）交织的MnTe纳米颗粒（简称MnTe@CNTs）来增强商用MnTe阴极的导电性，从而实现超快离子导电。稳定的电化学性能得益于层状MnTe和3D CNTs之间的协同作用，这可以改善电子/离子的循环扩散动力学。因此，MnTe@CNTs在0.1 a g-1时实现了427.2 mAh g-1的超高容量，在1 a g-1下超过200次循环的卓越容量保持率为97.6%。利用operando XRD和exsitu XPS光谱可以揭示锌的储存机制。MnTe作为一种新型阴极材料，在高性能azib中具有优异的储锌性能。

Three Dimensional CNTs Interweaved Layered MnTe Nanoparticles as a New Cathode For Aqueous Zinc Ion Battery.

Currently, the development of suitable transition metal chalcogenides (TMDs) for aqueous zinc ion batteries (AZIBs) is plagued by the terrible conductivity and electrochemical properties. Herein, a one-step ball milling method is applied to enhance the conductivity of commercial MnTe cathode by constructing three dimensional (3D) carbon nanotubes (CNTs) interweaved MnTe nanoparticles (abbreviated as MnTe@CNTs), which can achieve ultrafast ion conduction. The stable electrochemistry properties benefit from the synergistic effects between layered MnTe and 3D CNTs, which can improve the electrons/ions diffusion kinetics as cycling. So MnTe@CNTs achieves a ultra-high capacity of 427.2 mAh g^-1 at 0.1 A g^-1 and superior capacity retention of 97.6 % at 1 A g^-1 over 200 cycles. Zinc-storage mechanisms can be revealed with the aid of operando XRD and ex situ XPS spectra. MnTe as a new cathode presents superior Zn-storage ability for high-performance AZIBs.
