Lithium-Rich Anti-Perovskites as Super-Ionic Solid Electrolyte
Project Innovation and Overview
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. The result would allow EV batteries to increase the lithium ion transporting rate by 10-100 times and greatly enhance the energy density and power capacity of today’s lithium solid state batteries.
