Abstract

Recycling and utilizing waste biomass for anode materials in sodium-ion batteries is significant for both environmental sustainability and economic efficiency. In this study, a biomass-derived hard carbon material (MJ-HCl-1400) with a three-dimensional hollow tubular structure was prepared from agricultural waste Metaplexis japonica seed hair fibers via a simple acid treatment. Benefiting from this unique hollow architecture and the structural optimization of the carbon layers through acid washing, MJ-HCl-1400 demonstrates improved electrolyte infiltration and accelerated ion diffusion. In addition, MJ-HCl-1400 developed a SEI abundant in inorganic constituents during cycling. As a result, MJ-HCl-1400 exhibits excellent rate performance and cycling stability, delivering a high capacity of 229 mAh g^–1 at 3 A g^–1 and retaining 84.1% of its capacity after 2000 cycles at 2 A g^–1. Additionally, the plateau capacity contributes over 65% of the total capacity across various current densities, indicating its stability even under high-rate conditions. This study proposes an efficient and affordable carbon-based option for energy storage applications.

用刺槐籽毛纤维制备硬碳微管作为高性能钠离子电池负极材料。

回收和利用废弃生物质作为钠离子电池负极材料对环境可持续性和经济效益都具有重要意义。本研究以农业废弃物刺槐种子毛纤维为原料，经简单酸处理制备了具有三维空心管结构的生物质源硬碳材料MJ-HCl-1400。得益于这种独特的中空结构和通过酸洗优化的碳层结构，mj - hl -1400表现出改善的电解质渗透和加速的离子扩散。此外，mj - hl -1400在循环过程中产生了丰富的无机成分SEI。因此，mj - hl -1400表现出优异的倍率性能和循环稳定性，在3 a g-1下提供229 mAh g-1的高容量，在2 a g-1下循环2000次后保持84.1%的容量。此外，高原容量在各种电流密度下占总容量的65%以上，表明即使在高速率条件下也具有稳定性。本研究提出了一种高效、经济的碳基储能方案。
