Strategies to Boost the Safety and Ionic Conductivity of Lithium‐Ion Batteries Using Solid State Electrolytes: A Review

ABSTRACT The enormous potential of lithium‐ion batteries (LIBs) to provide environmentally sustainable practices and efficient energy storage has led to a rising interest in LIBs. Thermal runaway behaviors in LIBs, including high temperature, ejection, combustion, explosion, and the release of toxic gases, as well as thermal failure propagation in a battery pack, are both possible. Here, briefly mentioned about solid‐state electrolytes (SSE), which may use to make LIBs safer by reducing these risks. However, the SSE's ionic conductivity is subpar when compared to that of other liquid electrolytes, demanding modification. The authors have also focused on several SSE types in this review, including inorganic SSE, solid polymer electrolytes (SPEs), and composite solid electrolytes. Additionally, it was described how to enhance the ionic conductivity of SSEs at ambient temperature.
