Ionic Liquid‐Nanoparticle Hybrid Electrolytes and their Application in Secondary Lithium‐Metal Batteries

Ionic liquid-tethered nanoparticle hybrid electrolytes comprised of silica nanoparticles densely grafted with imidazolium-based ionic liquid chains are shown to retard lithium dendrite growth in rechargeable batteries with metallic lithium anodes. The electrolytes are demonstrated in full cell studies using both high-energy Li/MoS(2) and high-power Li/TiO(2) secondary batteries.
