Semiliquid electrolytes with anion-adsorbing metal-organic frameworks for high-rate lithium batteries.

Adding particles of metal-organic frameworks (MOFs) into liquid electrolytes leads to semiliquid electrolytes, where nanoporous MOFs enclose anions while facilitating lithium-ion conduction. The improved transport efficiency of lithium-ions in semiliquid electrolytes boosts effective reaction kinetics, mitigates polarization, and produces affinitive electrolyte-electrode interfaces, which afford enhanced cycle durability for high-rate lithium batteries.
