Polymer-ceramic based solid composite membranes as potential electrolytes for the lithium batteries

Over the past few years, lithium-ion batteries upsurged the performance of shelf life and dominated the global energy storage market. As the most significant energy storage devices, Li-ion batteries have several prominent characteristic features and advantages, such as high energy density, appreciable operating voltage, low self‐discharge rate, and long cycle life. Despite their supremacy in various fields, the expansion of existing commercial Li-ion batteries is facing several bottlenecks, such as burning, leakage, safety, and burst due to the relatively low-boiling point of the conventional organic liquid electrolytes. On the other hand, poor mechanical properties and low ionic conductivity are still the chief challenges in its commercial development. In this regard, solid composite electrolytes (SCEs) have shown their ability as potential electrolytes for Li-ion batteries. Moreover, they have proven as an attractive alternative option to mitigate or solve existing safety issues. SCEs combine the advantages of both inorganic ceramic electrolytes (ICEs) and solid polymer electrolytes (SPEs). SCEs possess high mechanical strength, acceptable ionic conductivity, good flexibility, high safety, low flammability, excellent thermal stability, and satisfactory interfacial contact with electrodes, which significantly enhances the overall electrochemical performance of the all‐solid‐state batteries compared to the single ICEs and SPEs. Various researchers have focused on implementing SCEs as potential electrolytes for Li-ion batteries. In this chapter, considerable emphasis has been made on the recent advances and achievements of polymer-ceramic-based solid composites membranes as potential electrolytes for Li-ion batteries.
