摘要

The development of anodes with high discharge capacity and excellent rate capability has attracted increasing attention. In this work, SnO2 nanoparticles embedded within chlorine-doped graphene (SnO2/Cl-rGO) were synthesized using a facile heat treatment method. Chlorine doping enhances the wettability of electrolyte to SnO2/Cl-rGO surface, thereby increasing the lithium-ion diffusion rate. Meanwhile, the doped chlorine atoms form strong interactions with lithium ions, leading to an increase in lithium storage sites. As a result, the SnO2/Cl-rGO exhibits a high discharge capacity of 610 mAh g–1 after 300 cycles at a current density of 0.2 A g–1. Following rate capability testing, the SnO2/Cl-rGO was cycled for another 200 cycles, and a discharge capacity of 603 mAh g–1 was retained, further demonstrating its potential as a high-performance anode material for lithium-ion batteries. This work on chlorine-doped graphene embedding SnO2 provides valuable insights for the preparation of next-generation high-performance anode materials.
