"introducing oxygen/ sulfur (divalent anions) into low-cost zirconium- based halide solid electrolyte’s crystal framework alters internal architecture, lowering lithium ions' energy barriers allowing them to move more freely through solid medium... improved lithium-ion mobility by two to four times compared to conventional zirconium-based electrolytes... cheaper, faster, room-temperature charging all-solid-state lithium batteries"
