摘要
石墨烯是目前商业化锂离子电池中使用最为普遍的一种负极材料,而且现在不断扩大的市场需求在逐渐对石墨负极材料的储锂性能提出了更好的要求与标准。文章主要针对锂离子电池基本原理和石墨嵌锂机制进行分析概述,同时也针对石墨负极材料理论比容量较低或者是电解液兼容性较差等问题进行研究,提出了一些石墨负极材料的改性方式,而主要改性方式则基本分为表面改性和结构调控两种,而针对两种方式存在的优势文中会详细阐述,并做详细的研究进展分析,最后对石墨负极材料的未来发展前景进行展望。本文主要对浅谈锂离子电池石墨负极材料的改性研究进展进行分析。
Graphene is currently the most commonly used anode material in commercial lithium-ion batteries,and the expanding market demand is gradually putting forward better requirements and standards for the lithium storage performance of graphite anode materials.This paper mainly analyzes and summarizes the basic principles of lithium-ion batteries and the mechanism of graphite lithium insertion,and also studies the problems of low theoretical specific capacity of graphite anode materials or poor electrolyte compatibility,and proposes some modification methods of graphite anode materials.The main modification methods are basically divided into two types:surface modification and structural regulation.The advantages of the two methods will be elaborated in the paper,and detailed research progress analysis will be made,and finally the future development prospects of graphite anode materials are prospected.This paper mainly analyzes the research progress of the modification of graphite anode materials for lithium-ion batteries.
