TL;DR: In this paper, the current status of spent lithium-ion battery recycling is summarized in light of the whole recycling process, especially focusing on the hydrometallurgy, which is used to extract metals or separate impurities from a specific waste stream so that the recycled materials or compounds can be further prepared by incorporating principles of materials engineering.

TL;DR: It is possible to provide a win-win solution to improve the recycling effectiveness of spent LIBs by using waste salt that is easily reused as the reductant, and ammonium chloride is found to be efficient and posing minor environmental impacts during the overall process.

TL;DR: In this article, the recycling of spent lithium-ion batteries (LIBs) is discussed, where the authors focus on reductive leaching, which often leads to total leaching rather than selective leaching of metals.

TL;DR: In this paper, a mechanochemical activation approach was proposed for the selective recycling of lithium and recovery of Ni0.5Mn0.3Co0.2O2 batteries.

TL;DR: In this article, a paired electrolysis method was designed to achieve the recycling of valuable metals from the spent lithium-ion batteries and the synthesis of persulfate synchronically, and high purity cobalt metal (>99.9%) was obtained from the leachate (catholyte) of the spent LIBs, and valuable persulfates were synthesized anolyte through a diaphragm electrolyzer.
