Abstract

Polyvinylidene fluoride (PVDF)/garnet composite polymer electrolytes (CPEs) have shown great potential in the development of solid-state lithium metal batteries (SSLMBs) due to their excellent flexibility, high ionic conductivity and superior mechanical strength. However, uneven dispersion of garnet fillers in CPEs would lead to deterioration of lithium metal batteries (LMBs) performance and severely limit their widespread application. Considering the rapidly growing research of addressing above-mentioned issue, herein, recent progress in the design and fabrication of uniformly dispersed fillers in PVDF/garnet CPEs for high-performance SSLMBs is summarized. We firstly analyze the mechanism for the aggregation of inorganic fillers, and provide a detailed introduction to the strategies for solving the uneven dispersion of nanoparticles in solid electrolytes. Moreover, we also comprehensively summarize their applications in PVDF/garnet electrolytes and their impact on the electrochemical performance of SSLMBs. Finally, the application challenges and future prospects of PVDF/garnet CPEs in SSLMBs were also proposed to promote their further development. It is anticipated that this review could inspire ongoing research interest in rational designing and fabricating novel CPEs for high-performance SSLMBs.

高性能固态锂电池用PVDF/石榴石复合电解质的均匀分散：基本原理、进展与展望

聚偏氟乙烯(PVDF)/石榴石复合聚合物电解质（cpe）由于其优异的柔韧性、高离子电导率和优异的机械强度，在固态锂金属电池（sslmb）的发展中显示出巨大的潜力。然而，石榴石填料在cpe中的分散不均匀会导致锂金属电池（lmb）性能的恶化，严重限制了其广泛应用。鉴于针对上述问题的研究正在迅速发展，本文综述了用于高性能sslmb的PVDF/石榴石cpe中均匀分散填料的设计和制造的最新进展。我们首先分析了无机填料聚集的机理，并详细介绍了解决纳米颗粒在固体电解质中分散不均匀的策略。此外，我们还全面总结了它们在PVDF/石榴石电解质中的应用及其对sslmb电化学性能的影响。最后，提出了PVDF/石榴石cpe在sslmb中的应用挑战和未来前景，以促进其进一步发展。期望本综述能够激发对高性能sslmb的合理设计和制造新型cpe的持续研究兴趣。摘要综述了高性能sslmb用pvdf /石榴石cpe中均匀分散填料的设计和制备的最新进展，并对其发展前景进行了展望。
