摘要(Abstract):

固态锂电池因其具备高能量密度、安全性好等优点而备受关注。作为固态锂电池最关键的组成部分,固态电解质(SSE)在提高固态锂电池的电化学性能方面起到至关重要的作用。聚偏二氟乙烯(PVDF)基固态聚合物电解质(SPE)具有优异的柔韧性、力学性能以及良好的加工性能,在固态锂电池的发展中展现出巨大的应用潜力。然而,PVDF基SPE仍存在离子电导率低、结晶度高等问题。本文基于SPE的离子传输机制和目前存在的缺点,详细介绍了PVDF基SPE设计策略的最新进展,重点总结了在有机分子改性、填料的设计与改性和结构调控等方面的研究进展。此外,本文介绍了PVDF基SSE在固态锂电池体系中的应用。最后,对PVDF基SPE的未来前景进行了展望。

关键词(KeyWords): 固态锂电池;;聚合物固态电解质;;聚偏二氟乙烯;;复合固态电解质
