Next-generation lithium-ion batteries (LIBs) will have a two to three times increase in energy density compared to today's technology due to the adoption of new cathode and anode materials. In addition, their safety properties need to be further enhanced to allow large-scale applications. In this context, new electrolytes with high lithium-ion (Li) conductivity as well as good stability should be developed. Recently, there has been a growing interest in developing nanohybrid electrolytes. By combining organic (polymers, ionic liquids) and/or inorganic (Li-conductive ceramics and glasses) functional constituents, a broad range of nanohybrid electrolytes with interesting chemical, mechanical and electrochemical properties have been designed and evaluated in different cell chemistry. This article aims to conduct a comprehensive review on the development of nanohybrid electrolytes in recent years (2012 to present). Specifically, we summarize and analyze the recent progress of gel-, inorganic- and polymer-based nanohybrid electrolytes with enhanced physicochemical properties and specified functionalities for their application in LIBs. Challenges and perspectives for future development of better nanohybrid LIB electrolytes are also discussed.
下一代锂离子电池（LIB）由于采用了新型阴极和阳极材料，其能量密度将比当今技术提高两到三倍。此外，为了实现大规模应用，还需要进一步提高其安全性能。在这种情况下，需要开发具有高锂离子（Li）电导率和良好稳定性的新型电解质。最近，人们越来越关注开发纳米复合电解质。通过将有机（聚合物、离子液体）和/或无机（Li 导电陶瓷和玻璃）功能成分结合在一起，设计和评估了具有有趣的化学、机械和电化学性能的各种纳米复合电解质，应用于不同的电池化学。本文旨在对近年来（2012 年至今）纳米复合电解质的发展进行全面综述。具体来说，我们总结和分析了凝胶、无机和聚合物基纳米复合电解质在增强物理化学性质和特定功能方面的最新进展，以将其应用于 LIB。还讨论了未来开发更好的纳米复合 LIB 电解质的挑战和展望。
