Abstract
Abstract The construction of a hollow structure could promote the diffusion of electrons and ions to improve the electrochemical performance of MoS 2 based materials for metal‐ion batteries. Herein, we summarize the preparation technique of MoS 2 hollow structural materials with different dimensions. The approaches to construct 0D hollow MoS 2 materials for electrodes of metal‐ion batteries can be divided into the hard template approach, soft template approach, self‐template approach, and template‐free approach. Among them, the hard template approach and self‐sacrifice template approach are controllable but complicated, the soft template approach and template‐free approach are simple and scalable but not controllable. Furthermore, as the electrode material of metal‐ion batteries including lithium‐ion battery, sodium‐ion battery, potassium‐ion battery or magnesium‐ion battery, the 0D hollow structural MoS 2 based materials could improve the diffusion kinetics of ion and electron and restrict the stack of MoS 2 . Furthermore, the 1D hollow MoS 2 can provide oriented electron diffusion along with the axial direction, and the 3D hollow MoS 2 can offer perforative pores for permeation of electrolytes and more active sites, which results in excellent rate capability and cycling stability. This paper could give inspiration for constructing MoS 2 hollow structural materials with different dimensions and provide a constructive suggestion for synthesizing hollow materials with excellent electrochemical performance.
