Solid-state electrolytes (SSEs) deliver inherent advantage of safety over the organic liquid system in rechargeable lithium batteries. However, the single use of polymer or ceramic SSEs can never meet the demand although great progress has been made in the past few years. Composite solid electrolytes (CSEs) composed of flexible polymers and brittle but active ceramics can take advantage of the individual system for solid-state lithium metal batteries (SSLMBs). According to the mass fraction of components, CSEs can be largely divided into two categories, namely “polymer rich” (PR) and “ceramic rich” (CR) systems with different internal structures and properties. This review provides a comprehensive and in-depth understanding of recent advances and limitations of both PR and CR electrolytes, mainly focusing on the ion conduction path based on interphase interactions and the structural designs of ceramic fillers/frameworks. Besides, the fact that PR and CR can bring the leverage between the electrochemical and the mechanical property has also been revealed. Moreover, it further prospects the possible route for future development of CSEs according to their rational design, conducive to the expectant industrialized application in SSLMBs.[展开] ...
