摘　　要：钠离子电池被认为是有前途的和高效的电化学储能系统。特别是在LIB的原材料(即钴,铜和锂)的成本迅速上涨的形势下,激发了研究人员对使用更便宜、丰度更高且分布均匀的钠离子的兴趣。硬炭材料由大量无序石墨微晶堆叠结构组成,拥有较大的层间距、结构稳定、丰富的纳米孔可为钠离子的嵌入和吸附提供更多空间,且制备工艺简单、环境友好,被认为是钠离子电池负极材料优质阳极材料,也是具有商业化前景的负极材料。本文结合硬炭材料结构特征分析其储钠机理及研究现状,总结并展望了硬炭材料在钠离子电池材料中应用的研究发展方向。Sodium-ion batteries are widely regarded as the most promising and efficient electrochemical energy storage system.In particular,the rapid increase in the cost of LIB’s raw materials,such as cobalt,copper and lithium,has stimulated interest in technologies that use cheaper,more abundant and uniformly distributed sodium ions.Hard carbon material composed of a disordered stack graphite crystallite structure,with larger layer spacing,stable structure,abundant nanopores,and features of simple preparation and friendly environment which can provide more space for adsorption of sodium ions,is considered as the optimal anode material for a sodium ion battery.In this paper,the mechanism of sodium storage and research status of hard carbon materials were analyzed based on the structural characteristics of hard carbon materials.Finally,research prospected are provided to guide the future development of hard carbon materials in sodium ion battery materials.
