摘　　要：低成本的碳材料被认为是一种有前途的钾离子电池负极材料,而常见的石墨由于狭窄的层间距导致倍率性能和循环稳定性不尽人意。通过将来源广泛、原料易得的生物质柳絮进行处理,得到了层间距为0.390 nm的无定形碳材料,并且可用作具备良好电化学性能的钾离子电池负极。因此,柳絮衍生的中空碳管在钾离子电池电极材料中具有潜在的应用潜力。Although the low-cost carbon materials has been considered as a promising anode for potassium ion batteries,common graphite possess unsatisfactory rate performance and cycle ability due to the narrow interlayer spacing.Herein,by processing a wide range of sources and readily available biomass catkins,an amorphous carbon with 0.390 nm interlayer spacing was obtained.It exhibited good electrochemical performance when used as the anode of potassium ion batteries.Thus,the catkins derived hollow carbon tubes have potential application in potassium ion batteries electrode materials.
