Abstract
Abstract Fascinating with high specific capacity and moderate lithiation potential, SnO x ‐based materials have been intensively investigated as one of the most promising anodes for lithium‐ion batteries. However, due to poor cycling stability, sluggish reaction kinetics, and limited electrochemical reaction reversibility, the development of SnO x ‐based anodes has been hindered. And the current preparation and modification routes for SnO x ‐based anodes lack direct and specific illustration. Herein, modification routes for SnO x ‐based anodes have been emphasized. Firstly, to provide more direct instructions, the tuning routes of morphological structure for SnO x ‐based electrodes (including slurry‐based and self‐supported) have been thoroughly discussed from the preparation perspective. Secondly, according to the properties of SnO x ‐based anodes, the phase structure design ideas have also been properly classified and organized for addressing chemical reaction kinetics or thermodynamic issues. Finally, for future‐oriented studies, new insights into the development and commercialization prospects of SnO x ‐based anodes are also provided. This review, with comprehensive information on SnO x ‐based anodes, aims to bring more specific guidance and valuable inspiration for peer researchers who are promoting the application of SnO x ‐based materials for energy conversion and storage devices
