The University of Nevada, Las Vegas (UNLV) is developing a solid-state, non-flammable electrolyte to make today's Li-Ion vehicle batteries safer. Today's Li-Ion batteries use a flammable liquid electrolyte--the material responsible for shuttling Li-Ions back and forth across the battery--that can catch fire when overheated or overcharged. UNLV will replace this flammable electrolyte with a fire-resistant material called lithium-rich anti-perovskite. This new electrolyte material would help make vehicle batteries safer in an accident while also increasing battery performance by extending vehicle range and acceleration.
