摘　　要：沥青是原油蒸馏或煤炼焦加工过程产生的一种大宗化学品,用途广泛但工业附加值较低,其作为炭前驱体制备包覆沥青等高品质人造炭材料,应用于锂离子电池负极及负极材料改性领域,具有重要的工业应用前景。文章从制备方法和市场前景等方面对包覆沥青进行了详细的综述与分析,并指出包覆沥青产品虽然具有优秀的市场前景,但是其制备方法仍需要进一步优化改进。Pitch is a kind of bulk chemical produced in the process of crude oil distillation or coal coking,which is widely used but has low industrial added value.As a carbon precursor system to prepare high-quality artif icial carbon materials such as coated pitch,it is used in the f ield of lithium ion battery anode and anode material modif ication,which has an important industrial application prospect.In this paper,the preparation methods and market prospects of coated pitch are reviewed and analyzed in detail.It is pointed out that although the coated pitch products have excellent market prospects,the preparation methods still need to be further optimized.
