摘要
Abstract
As a high-carbon material rich in aromatic structures,asphalt stands out as an excellent precursor material for sodium-ion battery carbon anodes due to its advantages of wide availability,high carbon content and low cost.However,asphalt-based carbon materials prepared by direct pyrolysis suffer from disadvantages such as high graphitization and narrow interlayer spacing,which limit sodium-ion storage capacity.Overcoming these limitations through structural and morphological regulations has become a key research focus in the field.Research progress on asphalt-based carbon anode materials were reviewed.The technical routes and modification mechanisms of structural regulation(pre-oxidation,soft/hard carbon composite and heteroatom doping)and morphological regulation(construction of porous structures and carbon nanofiber membranes)was mainly introduced.The structure-property relationship between microstructure and sodium storage performance and the advantages and disadvantages of various regulation methods were analyzed.Finally,insights into future research directions of asphalt-based carbon anode materials were provided from the perspectives of fundamental science,material design and industrial application,respectively.关键词
