Flame-Retardant Electrolytes for Safer Lithium-Ion Batteries A non-flammable, high-stability electrolyte system that makes lithium-ion batteries safer and more reliable in extreme environments. Technology Summary: A novel class of stabilized phosphoranimines has been developed as air- and water-stable room-temperature ionic liquids (RTILs) with flame-retardant properties and thermal stability beyond 150 °C. These compounds address long-standing limitations of traditional phosphoranimines, which are typically reactive intermediates, by introducing new structural motifs that enable safe handling and practical use. Critically, the materials can solubilize lithium salts and maintain stability in electrochemical environments, making them strong candidates as next-generation electrolytes for lithium-ion batteries. Supporting research on phosphazene-based electrolytes for lithium batteries provides additional context for this development: https://www.sciencedirect.com/science/article/pii/S001346861631091X Problem Addressed Current lithium-ion electrolytes are based on organic carbonates, which are flammable, volatile, and thermally unstable, creating safety and performance limitations in ...
