Therefore, the amount of wasted LIBS will also increase as a result. The used LIBS contain large amounts of cobalt, lithium, nickel, manganese, copper, aluminum and other non-ferrous metal elements and poisonous and harmful materials, such as LiPF6 and PVDF. So it plays a significance role in the resource recycling and environmental disposing. This paper reviews the current status of the recycling technologies of spent LIBS. Through reviewing the recycling technologies of recent years, the main treating process of spent LIBS has often classified into pretreatment, secondary treatment, and further treatment three steps, with the last two steps being the mo
