Organic-inorganic composite electrolytes for all-solid-state lithium batteries

Solid electrolytes are considered to be a promising candidate to replace traditional liquid electrolytes due to their enhanced safety and cycling performance. Unfortunately, the low ionic conductivity of solid electrolytes and the poor interfacial contact at electrolyte/electrode interface limit their application in Li batteries. Thus, developing novel electrolyte systems based on ceramic filler-incorporated polymer matrices with improved mechanical strength, ionic conductivity and wide electrochemical window is the ultimate solution for all-solid-state lithium batteries. Recently, composite solid electrolytes containing ceramic fillers and polymer electrolytes have drawn a lot of attention. Designing and optimizing the structure of composite solid electrolytes is of great importance to boost the overall performance. The multiple advantages of organic-inorganic composite electrolytes assembled in all-solid-state lithium batteries are discussed in the text. Research progress on structural design of composite solid electrolytes from the perspective of meeting different performance demands considering Li-ion transport mechanism, Li dendrite suppression and interface stability are summarized. The future development trend and direction of organic-inorganic composite electrolytes are also mentioned.
