摘　　要：在应对能源危机和实现环境可持续发展的大背景下,能源储存系统受到了广泛关注。随着锂资源的快速消耗及其分布不均带来的挑战,具有相似电化学性质的钠离子电池(SIBs)逐渐成为研究热点。硬碳(HC)材料因其资源丰富、成本效益高和碳转化率高,已经成为SIBs中极具潜力的负极材料之一。煤基硬碳(CHC)因其低廉的成本和高碳转化率,成为HC前驱体中极具竞争力的材料之一。综述了近几年关于CHC材料的制备策略、优化改性及其电化学性能方面的研究成果,并对CHC材料的发展前景、应用和研究方向进行了展望。In the context of addressing the energy crisis and realizing environmental sustainability,energy storage systems have received much attention.With the challenges posed by the rapid depletion of lithium resources and its uneven distribution,sodiumion batteries(SIBs)with similar electrochemical properties have gradually become a research hotspot.Hard carbon(HC)materials have become one of the highly promising anode materials for SIBs due to their abundance of resources,cost‐effectiveness and high carbon conversion.Coal‐based hard carbon(CHC)has become one of the competitive materials in HC precursors due to its low cost and high carbon conversion.This article reviews recent research on the preparation strategies,optimization modifications,and electrochemical properties of coal‐based hard carbon materials.Furthermore,we discuss the development prospects and research directions for coal‐based hard carbon materials.
