“…In the alkali -acid leaching process, the cathode was first treated with 10% (w/w) NaOH at 30 o C to dissolve Al, followed by reductive leaching of ~97% Co and 100% Li with H 2 SO 4 and H 2 O 2 (Nan et al, 2005;Ferreira et al, 2009). Acorga M5640 and Cyanex 272 were used to selectively extract and recover 98% Cu and 97% Co, respectively from the solutions.…”

“…The results showed that sulfuric acid, citric acid, and malic acid exhibited higher leaching efficiency compared with the other six organic acids, at 95.8%, 89.9%, and 86.69%, respectively. The carboxyl and hydroxyl groups in citric and malic acid are expected to give rise to H + in distilled water [23,24]; therefore, dissociated carboxyl groups will react with cobalt ions upon the addition of the reducing agent H 2 O 2 , the ability of which to enhance the aqueous solubility of cobalt ions is also well known [22,25]. Among these organic acids, malic acid was chosen in this study for further investigation of a one-pot leaching and precipitation process to re-synthesize LiCoO 2 , thanks to its advantages in price and accessibility over citric acid.…”

A complete recycling process for the cathode material of spent lithium-ion batteries is demonstrated with a simple two-step process comprised of one-pot cobalt recovery to nanostructured materials and single step synthesis of LiCoO 2 . For the facile and efficient recovery of cobalt, we employ malic acid as a leaching agent and oxalic acid as a precipitating agent, resulting in nanostructured cobalt oxalate. X-ray diffraction and Fourier transform infrared spectroscopy (FT-IR) analysis clearly show that cobalt species are simultaneously leached and precipitated as cobalt oxalate with a high yield of 99.28%, and this material can then be used as a reactant for the synthesis of LiCoO 2 for use as a cathode material. In addition to its advantages in simplifying the process, the proposed method allows for not only enhancing the efficiency of cobalt recovery, but also enabling reaction without a reducing agent, H 2 O 2 . Through successive single-step reaction of the obtained cobalt oxalate without any purification process, LiCoO 2 is also successfully synthesized. The effect of the annealing temperature during synthesis on the nanostructure and charge-discharge properties is also investigated. Half-cell tests with recycled LiCoO 2 exhibit a high discharge capacity (131 mA·h·g −1 ) and 93% charge-discharge efficiency.

“…The recycling of valuable metals from spent LIBs mainly involves mechanical processing, thermal treatment and chemical processing, particularly acid or alkaline leaching, precipitation, separation and electrochemical recovery [6][7][8][9][10]. Because of the demand for high purity metals in the recycling of spent LIBs, more attention has been focused on solvent extraction, which can meet the economic and performance requirements to replace conventional separation processes, particularly precipitation methods.…”

− The present paper deals with the extractive separation and selective recovery of nickel and lithium from the sulfate leachate of cathode scrap generated during the manufacture of LIBs. The conditions for extraction, scrubbing and stripping of nickel from lithium were optimized with an aqueous feed containing 2.54 kg·m -3 Ni and 4.82 kg·m -3 Li using PC-88A. Over 99.6% nickel was extracted with 0.15 kmol·m -3 PC-88A in two counter-current stages at O/A=1 and pH=6.5. Effective scrubbing Li from loaded organic was systematically studied with a dilute Na 2 CO 3 solution (0.10 kmol·m). The McCabe-Thiele diagram suggests two counter-current scrubbing stages are required at O/A=2/3 to yield lithium-scrubbing efficiency of 99.6%. The proposed process showed advantages of simplicity, and high purity (99.9%) nickel sulfate recovery along with lithium to ensure the complete recycling of the waste from LIBs manufacturing process.
