杂原子掺杂石墨烯在锂离子电池负极中的研究进展
Research progress on heteroatom-doped graphene in the negative electrode of lithium-ion batteries
摘要
Abstract
Graphene has garnered considerable attention in the field of lithium-ion battery negative electrode materials owing to its unique two-dimensional structure and excellent performance.However,its inherent chemical inertness and aggregation tendency limit its application.Heteroatom doping represents a pivotal strategy for optimizing graphene's electrochemical performance.This study reviews the preparation methods,lithium storage mechanisms,and performance advantages of graphene doped with various heteroatoms,including nitrogen,boron,sulfur,phosphorus,silicon,and halogens.Heteroatom-doped graphene is divided into single-doped and codoped graphene based on the number of doping elements.The effects of doping are primarily influenced by factors such as atom radius,electronegativity,element combinations,and doping method.Single-doped graphene can markedly enhance electrochemical performance by regulating electronic properties,introducing defects and active sites,and expanding interlayer spacing.Codoped graphene overcomes single-doping limitations through synergistic electronic,spatial,and stability effects.Overall,heteroatom doping,particularly codoping,significantly improves the lithium storage capacity,rate performance,and cycling stability of graphene through multimechanism synergy,providing valuable guidance for designing high-performance negative electrode materials for lithium-ion batteries.关键词
