Carbon materials, including graphite, hard carbon, soft carbon, graphene, and carbon nanotubes, are widely used as high-performance negative electrodes for sodium-ion and potassium-ion batteries (SIBs and PIBs). Compared with other materials, carbon materials are abundant, low-cost, and environmentally friendly, and have excellent electrochemical properties, which make them especially suitable for negative electrode materials of SIBs and PIBs. Compared with traditional carbon materials, modifications of the morphology and size of nanomaterials represent effective strategies to improve the quality of electrode materials. Different nanostructures make different contributions toward improving the electrochemical performance of electrode materials, so the synthesis of nanomaterials is promising for controlling the morphology and size of electrode materials. This paper reviews the progress made and challenges in the use of carbon materials as negative electrode materials for SIBs and PIBs in recent years. The differences in Na⁺ and K⁺ storage mechanisms among different types of carbon materials are emphasized.

碳材料作为钠、钾离子电池负极的研究进展

碳材料，包括石墨、硬碳、软碳、石墨烯和碳纳米管，被广泛用作钠离子和钾离子电池（SIBs和PIBs）的高性能负极。与其他材料相比，碳材料储量丰富、成本低廉、环境友好，并具有优异的电化学性能，特别适用于SIBs和PIBs的负极材料。与传统碳材料相比，改变纳米材料的形貌和尺寸是提高电极材料质量的有效策略。不同的纳米结构对提高电极材料的电化学性能有不同的贡献，因此，纳米材料的合成有望用于控制电极材料的形貌和尺寸。本文综述了近年来碳材料作为SIBs和PIBs负极材料所取得的进展和面临的挑战。Na的区别⁺和K ⁺不同类型的碳材料之间的储存机制被强调。
