Spent lithium-ion batteriesDischargeRecyclingEnvironmentally friendlyLithium-ion batteries have been widely used in electronic products. However, disposal of these spent LIBs containing heavy metals will result in environmental pollution. Therefore, the recycling of spent LIBs has become highly desirable from...

Based on the structural characteristics of the anodes of lithium-ion batteries, an improved Hummers’ method is proposed to recycle the anode materials of spent lithium-ion batteries into graphene. In order to effectively separate the active material from the copper foil, water was selected as an...
Since the 1990s, lithium ion batteries (LIBs) have been widely used in portable electronic devices and electric vehicles [1], [2], [3] because of their high energy density, long storage life, small volume, light weight, low self-discharge efficiency, non-memory effect, wide range of applic...
a recovery procedure of spent lithium-ion secondary battery is proposed as follows:"splitting →pretreating the positive electrode material with NMP →leaching the cobalt in positive electrode material→ removing impurities extracted with P204 →separating cobalt ion from lithium ion extracted with P507"...
LiCoO2 powders were prepared by co-precipitation process using the cobalt and lithium recovered from spent lithium ion batteries as raw materials through cobalt carbonic acid and lithium carbonic acid, taking sodium carbonate as precipitator and ethylene alcohol as dispersant. The precursor was thermally...

The novel leaching system was validated using black mass from end-of-life batteries and manufacturing scrap from battery producers, representing the two dominant black mass types processed in the market. The leaching study demonstrated that the highest cobalt and lithium recoveries of 100% and 99.8%...
Deep eutectic solvent (DES), as an innovative green leaching agent, demonstrates significant potential for recycling spent lithium-ion battery cathode materials [11–19]. It provides benefits including environmental sustainability, adjustable structure, and convenient regeneration compared to conventional ...
A well characterized cathode material (LiCoO2) recovered from spent lithium-ion battery is dissolved in aqueous mixture of citric acid (chelating agent) and ascorbic acid (reductant) at 80 °C. The dissolution proceeds with a reductive-complexing mechanism, and complete dissolution occurs in about ...
