Recent progress on hierarchical MoS2 nanostructures for electrochemical energy storage

Abstract

Hierarchical MoS₂ nanostructures are of increasing importance in energy storage via batteries or supercapacitors. Herein, the various hierarchical MoS₂ materials used as electrochemical electrodes are reviewed in detail by classifying the MoS₂ into free-standing and substrate-supported hierarchical structures. The growth methods, morphologies, surface area, and electrochemical performance of the hierarchical MoS₂ structures, including nanospheres, nanotubes, and nanoboxes are highlighted. Ascribed to the porous features and interconnected nanosheets, the hierarchical architectures demonstrated a large surface area and high structural stability, resulting in a high rate capacity and long cycling life. Based on the spotlight of applications for electrochemical energy storage, the recent progress of hierarchical MoS₂ with efficient electrochemical properties is reviewed. Moreover, further research prospects and challenges of hierarchical MoS₂ in energy storage are proposed.
