Phosphorus‐Based Flame‐Retardant Electrolytes for Lithium Batteries

Abstract The increasing demand for high‐performance energy storage systems has driven a significant focus on developing electrolytes for lithium‐ion batteries (LIBs), known for their high energy density and cycle stability. Organic electrolytes play a crucial role in enhancing battery performance due to their high ionic conductivity and wide electrochemical stability. However, their flammability and volatility pose serious safety risks, including thermal runaway and fire hazards. To address these issues, research is advancing on flame‐retardant electrolytes, particularly fluorine (F)‐based and phosphorus (P)‐based compounds. F‐based flame‐retardants work by interrupting flame propagation through radical…
