冻干法制备氮掺杂石墨烯负载Sb2S3钠离子电池负极材料
Synthesis of Nitrogen-Doped Graphene-Supported Antimony Sulfide Composite via Freeze-Drying Method for Sodium Ion Battery Anodes
摘要
Abstract
Sodium-ion batteries(SIBs)hold great potential for energy storage applications due to the abundant sodium re-serves and low cost.Conversion-type Sb2S3 has attracted significant research attention owing to its high theoretical specific capacity.In this study,a nitrogen-doped graphene-supported antimony sulfide composite(Sb2S3@NG)was synthesized via a freeze-drying method.The introduction of nitrogen-doped graphene facilitates the construction of a highly interconnected three-dimensional conductive network,providing additional buffer space to accommodate volume expansion.The study re-sults demonstrated that Sb2S3@NG exhibited a high specific capacity of 1 079.7 mA·h/g at a current density of 0.1 A/g,with an initial Coulombic efficiency of 86.3%.Furthermore,after 150 cycles at 0.5 A/g,the composite retained a reversible cap-acity of 578.8 mA·h/g,corresponding to a capacity retention rate of 82.5%.关键词
