| Abstract Scope |
There is a concern that the next generation of energy storage devices will require certain properties that cannot be achieved using current electrolytes. Hybrid electrolyte materials offer the opportunity to bridge any gaps by combining the advantage of fast ion transport of liquid electrolytes while incorporating additional properties provided by the solid host. Ionogel electrolytes which consist of an ionic liquid confined in a solid matrix via hybridization, retain the excellent electrochemical properties of ionic liquids: wide electrochemical window, high ionic conductivity, negligible vapor pressure, thermal stability, and nonflammability. Ionogels also benefit from the properties of the solid host in its thermal and dimensional stability, and enhanced mechanical properties. In this presentation, we review our recent work on the development of ionogel electrolytes for both sodium-ion and lithium-ion batteries. These hybrid materials have now been successfully adapted to anode-free designs, possessing properties beyond that of ceramic solid electrolytes. |
