Abstract

The rapid development of electric vehicles has raised higher demand on the energy density and safety of current lithium battery system. Solid-state lithium metal batteries are considered one of the most promising next-generation energy storage technologies due to their high energy density and high safety. High-performance solid electrolyte is the key to the development of solid-state lithium metal batteries. Among the reported solid electrolytes, composite solid electrolytes have gained significant attention for combining the advantages of both solid polymer electrolytes and inorganic solid electrolytes. This review provides a critical and systematic discussion on the current progress of composite solid electrolytes, focusing on their structural design and ion conduction mechanism. Furthermore, the critical challenges and future perspectives of composite solid electrolytes are also prospected to advance their practical application in developing high-performance solid-state lithium metal batteries.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
