Abstract

Bio-based carbon fibers derived from lignin have gained significant attention due to their diverse and renewable sources, ease of extraction, and low cost. However, the current limitations of low specific surface area and insufficient electrical conductivity hinder the widespread application of lignin-derived carbon fibers (LCFs). In this work, highly conductive and porous LCFs are developed through melt-blowing, pretreatment, and carbonization processes. The effects of the carbonization temperature and heating rate on the structures and properties of the LCFs are systematically investigated. The resultant LCFs exhibit high electrical conductivity (71 400 S m⁻¹) and a large specific surface area (923 m² g⁻¹). The assembled lithium-ion battery based on the LCF anodes demonstrates a long cycle life of >800 cycles and a high specific capacity of 466 mA h g⁻¹. The findings of this study hold practical significance for promoting the utilization of lignin in the fields of energy storage, adsorption, and beyond.

高导电性和多孔性木质素衍生碳纤维。

木质素衍生的生物基碳纤维因其来源多样、可再生、易于提取和成本低而备受关注。然而，目前低比表面积和电导率不足的限制阻碍了木质素衍生碳纤维（LCFs）的广泛应用。在这项工作中，通过熔融吹塑、预处理和碳化工艺开发了高导电性和多孔的LCF。系统地研究了碳化温度和加热速率对LCFs结构和性能的影响。所得的LCF表现出高电导率（71 400s-1）和大的比表面积（923m2g-1）。基于LCF阳极的组装锂离子电池具有>800次循环的长循环寿命和466mAhg-1的高比容量。该研究结果对促进木质素在储能、吸附等领域的利用具有现实意义。

期刊介绍： Materials Horizons is a leading journal in materials science that focuses on publishing exceptionally high-quality and innovative research. The journal prioritizes original research that introduces new concepts or ways of thinking, rather than solely reporting technological advancements. However, groundbreaking articles featuring record-breaking material performance may also be published. To be considered for publication, the work must be of significant interest to our community-spanning readership. Starting from 2021, all articles published in Materials Horizons will be indexed in MEDLINE©. The journal publishes various types of articles, including Communications, Reviews, Opinion pieces, Focus articles, and Comments. It serves as a core journal for researchers from academia, government, and industry across all areas of materials research. Materials Horizons is a Transformative Journal and compliant with Plan S. It has an impact factor of 13.3 and is indexed in MEDLINE.
