Abstract
Valuable elements in lithium-ion batteries is a very significant secondary resource. Based on the recovery and recycling of the spent all-solid-state lithium-ion batteries in the future, we explore extracting valuable lanthanum, zirconium, and lithium elements from the solid electrolyte tetragonal phase LLZO by the leaching with the dilute sulfuric, and then by precipitation methods of double salts and carbonate salt, and recrystallization, respectively.
