Due to the shortage of energy resources and the problem of environmental pollution ,it is essential to adopt proper ways to develop new energy storage materials to solve the problem .Lithium ion battery has been widely used ,but the content of lithium elements on the earth is less ,which limited the development of lithium-ion battery .The chemical properties of sodium and lithium are similar ,which means sodium can replace the lithium as a new generation of energy material .Carbon material for sodium anode storage can be divided into natural graphite ,graphene ,soft carbon materials and hard carbon materials .This review aims to introduce the definition ,problems and solutions of carbon materials ,which has significant influence on modification of carbon mate-rials and applications in sodium ion batteries .%由于能源资源短缺和环境问题,开发新型储能材料迫在眉睫.锂离子电池应用广泛,但其在地壳中的含量较低,限制了它的发展.钠与锂具有相似的化学性质,可以替代锂成为新一代储能材料.碳基储钠负极材料分为天然石墨、石墨烯、软碳材料和硬碳材料.重点介绍了这些碳材料的定义、存在的问题和解决方案,对碳材料的改性及其在钠离子电池中的应用有一定的指导意义.
