摘要
Fascinating with high specific capacity and moderate lithiation potential, SnOx-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 SnOx-based anodes has been hindered. And the current preparation and modification routes for SnOx-based anodes lack direct and specific illustration. Herein, modification routes for SnOx-based anodes have been emphasized. Firstly, to provide more direct instructions, the tuning routes of morphological structure for SnOx-based electrodes (including slurry-based and self-supported) have been thoroughly discussed from the preparation perspective. Secondly, according to the properties of SnOx-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 SnOx-based anodes are also provided. This review, with comprehensive information on SnOx-based anodes, aims to bring more specific guidance and valuable inspiration for peer researchers who are promoting the application of SnOx-based materials for energy conversion and storage devices
