본원에는, 배터리 재료를 차아염소산칼슘 염을 포함하는 수성 매질과 접촉시켜 혼합물을 형성하는 단계, 상기 혼합물에서 고체를 액체로부터 분리하여 리튬 이온을 포함하는 수용액을 수득하는 단계를 포함하는 배터리 재료로부터 리튬을 제거하는 방법이 개시된다. 또한, 리튬 이온 배터리 재료를 재활용하는 방법도 개시된다. Disclosed herein are processes for removing lithium from a battery material comprising contacting the battery material with an aqueous medium comprising calcium hypochlorite salts to form a mixture, and separating in the mixture solids from liquids to obtain an aqueous solution comprising lithium ions. Also disclosed are processes for recycling lithium ion battery materials.
