近日，青岛科技大学赵英杰团队报道了共价有机骨架/碳纳米管复合材料增强锂离子电池性能。相关论文于2026年1月7日发表在《中国高分子科学杂志》上。

研究组重点关注由共价有机框架（COFs）与碳纳米管（CNTs）集成而成的电极材料在锂离子电池应用中的开发与优化。研究结果表明，将CNTs掺入COFs中，通过降低电荷转移电阻和加速电荷传输动力学，显著提升了其电化学性能。

令人印象深刻的是，COFs/CNT复合材料在低电流密度0.05 A·g^–1下就展现出了307 mAh·g^–1的高比容量，且即使在高电流密度下也保持了强大的容量保持能力。此外，该复合材料还表现出优异的循环稳定性和结构鲁棒性，在1000次充放电循环后仍保持显著容量。

Abstract: This study focuses on the development and optimization of electrode materials composed of covalent organic frameworks (COFs) integrated with carbon nanotubes (CNTs) for lithium-ion battery applications. The findings reveal that incorporating CNTs into COFs markedly enhances their electrochemical performance by reducing charge transfer resistance and accelerating charge transport kinetics. Impressively, the COFs/CNT composites delivered a high specific capacity of 307mAh·g–1 at a low current density of 0.05A·g–1 and maintained strong capacity retention even at elevated current densities. Furthermore, the composites demonstrated outstanding cycling stability and structural robustness, retaining significant capacity after 1000 charge/discharge cycles.
