In advanced polymer-based solid-state lithium-ion batteries, gel polymer electrolytes have been used, which is a combination of both solid and polymeric electrolytes. The use of these electrolytes enhanced the battery performance and generated potential up to 5 V.
Electrolytes act as a transport medium for the movement of ions between electrodes and are also responsible for the enhanced performance and cell stability of batteries. Cell voltage and capacity represent energy density, while coulombic efficiency and cyclic stability indicate energy efficiency.
The electrolyte is a key component in batteries, with properties that have far-reaching effects on the battery performance. Yet, according to general design principles of the electrolyte, operation under such harsh environments seems infeasible. In response, battery communities are scrambling to develop new concepts and theories.
Such knowledge has been driving a series of new electrolyte concepts for emerging battery chemistries. Efforts are being made to develop battery chemistries that promise high energy density, rapid charging, low cost, high sustainability, and independence from elements or materials of high geopolitical or ethical risks.
Solid electrolytes are growing fast as next-generation battery electrolyte because of the high power and energy density they promise along with excellent safety features. However they also need to possess good electrochemical and mechanical properties for their commercialization. For achieving this, the importance of fillers is highlighted.
This PIL based electrolyte showed excellent battery performance in a LIB with high thermal stability up to about 330 °C, low Tg (glass transition temperature) at near 54 °C and ionic conductivity as high as 10 −4 S cm −1 at low medium temperature.
