ABSTRACT

The development of quasi-solid-state electrolytes (QSSEs) represents the prime direction in making high power lithium-ion batteries (LIBs) for sustainable energy storage devices. The development of flexible and wearable electronics has brought a need for safe LIBs with a long operational period with mechanical robustness. In order to construct LIBs’ high capacity and long-term stable system, electrolytes attain special emphasis, as they are placed between anode and cathode, and hence, efforts are ongoing to discover an efficient electrolyte system. In order to increase ionic conductivity, the system is chosen in such a manner that it provides high charge carrier mobility along with high electrolyte uptake concentration. Apart from ionic conductivity, the electrochemical window of QSSE would be a critical parameter, as it decides the total operational potential window of LIBs. Apart from chemical stability, excellent thermal stability is also a desirable parameter, as LIBs must withstand the heat generated due to short circuit, overcharge, improper operation, or external thermal abuse.
