对话吴大勇:一位科学家的锂电产业“破壁”
高工锂电· 2026-02-16 12:09
真正的问题是MOF是否能打破电池性能边界创造增益? 2025年诺贝尔化学奖,将金属有机框架材料(MOF)推至聚光灯下。2025年10月,2025年诺贝尔化学奖授予了北川进、理查德·罗布森与奥马尔·亚 吉,以表彰他们在金属有机框架——MOF领域的奠基性贡献。 当电池系统同时追求更高能量密度、更高安全性与更长寿命时,单一惰性材料已难以持续满足需求。 膜体系开始从"被动承载",转向"功能参与"。 MOF的价值,正是在这一节点上被系统性看见。 一方面,MOF具备明确的电性特征和可设计结构,能够影响电解质解离行为与锂离子迁移过程;另一方面,其孔道结构与官能团设计,为捕获副反 应产物、改善界面环境提供了材料基础。 但国内首个对MOF进行产业化探索的 蓝廷新能源董事长、中国科学院理化技术研究所研究员吴大勇 看来,聚光灯之下只是一个原本已在推进中的材 料路线,开始被更广泛,也更严肃地讨论。 在接受高工锂电专访时,吴大勇多次强调,MOF并非"横空出世"的新材料,其真正的问题是它是否能打破电池性能边界创造增益,并实现稳定生 产。 一位 隔 膜研究者,为何最终选择MOF 吴大勇选择在锂电产业发展MOF,源于他对电池膜体系长期演进的 ...
