Abstract:
... As a typical urban mineral resource, spent lithium ion batteries (LIBs) contain abundant valuable metal resources, such as Li, Co, Mn and Ni, but facile separation with environmental benignity is challenging. Although the organic acid leaching method has been proposed to address this issue, its application is still hindered by the limitations of low leaching efficiency, high acid consumption and r ...
