Solid composite electrolytes (SCEs) that combine the advantages of solid polymer electrolytes (SPEs) and inorganic ceramic electrolytes (ICEs) present acceptable ionic conductivity, high mechanical strength, and favorable interfacial contact with electrodes, which greatly improve the electrochemical performance of all-solid-state batteries compared to single SPEs and ICEs. However, there are many challenges to overcome before the practical application of SCEs, including the low ionic conductivity less than 10-3 S cm-1 at ambient temperature, poor interfacial stability, and high interfacial resistance, which greatly restrict the room temperature performance. Herein, the advances of SCEs applied in all-solid-state lithium batteries are presented, including the Li ion migration mechanism of SCEs, the strategies to enhance the ionic conductivity of SCEs by various morphologies of ICEs, and construction methods of the low resistance and stable interfaces of SCEs with both cathode and anode. Finally, some typical applications of SCEs in lithium batteries are summarized and future development directions are prospected. This work presents how it is quite significant to further enhance the ionic conductivity of SCEs by developing the novel SPEs with the special morphology of ICEs for advanced all-solid-state lithium batteries.

锂电池陶瓷/聚合物复合固体电解质的进展与展望。
固体复合电解质（SCE）结合了固体聚合物电解质（SPE）和无机陶瓷电解质（ICE）的优点，具有良好的离子电导率、较高的机械强度以及与电极良好的界面接触，大大提高了全固体的电化学性能-状态电池与单个 SPE 和 ICE 相比。然而，SCE在实际应用之前还需要克服许多挑战，包括常温下低于10-3 S cm-1的离子电导率低、界面稳定性差、界面电阻高，极大地限制了室温性能。本文介绍了SCE在全固态锂电池中的应用进展，包括SCE的锂离子迁移机制、通过不同形貌的ICE来增强SCE的离子电导率的策略以及低电阻和低电阻的构建方法。 SCE与阴极和阳极的稳定界面。最后，总结了SCE在锂电池中的一些典型应用并展望了未来的发展方向。这项工作展示了如何通过开发具有ICE特殊形貌的新型SPE来进一步提高SCE的离子电导率，对于先进的全固态锂电池具有重要意义。
