Abstract

Developing high-capacity carbon-based anode materials is crucial for enhancing the performance of lithium-ion batteries (LIBs). In this study, we presented a nitrogen-doped lignin mesoporous carbon/nickel/nickel oxide (NHMC/Ni/NiO) nanocomposite for developing high-capacity LIBs anode materials through carbonization and selective etching strategies. The synthesized NMHC/Ni/NiO-0.33 composite exhibited a highly regular microstructure with well-dispersed Ni/NiO particles. The composite had a surface area of 408 m2⋅g−1, a mesopore ratio of 75.0%, and a pyridine–nitrogen ratio of 58.9%. The introduction of nitrogen atoms reduced the disordered structure of lignin mesoporous carbon and enhanced its electrical conductivity, thus improving the lithium storage capabilities of the composite. Following 100 cycles at a current density of 0.2 A⋅g−1, the composite demonstrated enhanced Coulomb efficiency and rate performance, achieving a specific discharge capacity of 1230.9 mAh⋅g−1. At a high-current density of 1 A⋅g−1, the composite exhibited an excellent specific discharge capacity of 714.6 mAh⋅g−1. This study presents an innovative method for synthesizing high-performance anode materials of LIBs.

氮掺杂木质素介孔碳/镍/氧化物纳米复合材料具有优异的锂存储性能
开发高容量碳基负极材料是提高锂离子电池性能的关键。在这项研究中,我们提出了一种氮掺杂木质素介孔碳/镍/氧化镍(NHMC/Ni/NiO)纳米复合材料,通过碳化和选择性蚀刻策略来开发高容量的锂离子电池阳极材料。合成的NMHC/Ni/NiO-0.33复合材料具有高度规则的微观结构,Ni/NiO颗粒分布良好。该复合材料的表面积为408 m2⋅g−1,介孔率为75.0%,吡啶氮比为58.9%。氮原子的引入降低了木质素介孔碳的无序结构,增强了其导电性,从而提高了复合材料的储锂能力。在0.2 a⋅g−1的电流密度下,经过100次循环后,该复合材料的库仑效率和倍率性能均有所提高,比放电容量达到1230.9 mAh⋅g−1。在1 a⋅g−1的大电流密度下,复合材料具有714.6 mAh⋅g−1的优异比放电容量。本研究提出了一种合成高性能锂离子电池负极材料的创新方法。图形抽象
