Solid-state batteries (SSBs) have recently been revived to increase the energy density and eliminate safety concerns associated with conventional Li-ion batteries with flammable liquid electrolytes. To achieve large-scale, low-cost production of SSBs as soon as possible, it would be advantageous to modify the mature manufacturing platform, involving slurry casting and roll-to-roll technologies, used for conventional Li-ion batteries for application to SSBs. However, the manufacturing of SSBs depends on the development of suitable solid electrolytes. Inorganic–polymer composite electrolytes combine the advantages of inorganic and polymer solid electrolytes, making them particularly suitable for the mass production of SSBs. In this Review, we discuss the properties of solid electrolytes comprising inorganic–polymer composites and outline the design of composite electrolytes for realizing high-performance devices. We also assess the challenges of integrating the composite electrolytes into batteries, which will enable the mass production of SSBs.

为大规模生产固态电池量身定制无机聚合物复合材料

固态电池(SSB)最近已经恢复使用,以提高能量密度并消除与具有易燃液体电解质的传统锂离子电池相关的安全隐患。为了尽快实现大规模,低成本的SSB生产,修改成熟的制造平台(包括用于SSB的常规锂离子电池的浆料浇铸和卷对卷技术)将是有利的。然而,SSB的制造取决于合适的固体电解质的开发。无机-聚合物复合电解质结合了无机和聚合物固体电解质的优点,使其特别适合于SSB的批量生产。在这篇评论中,我们讨论了包含无机-聚合物复合材料的固体电解质的性能,并概述了用于实现高性能器件的复合电解质的设计。我们还评估了将复合电解质集成到电池中的挑战,这将使SSB得以批量生产。
