“…The powder obtained was burnt to remove PVdF, followed by dissolution to produce sulfate solution. Cobalt in the solution was deposited as oxalate, while Acorga M5640 and Cyanex272 (di-(2,4,4 trimethyl pentyl) phosphoric acid) were used to selectively extract small quantities of Cu 2+ , Co 2+ (Nan et al, 2005) and Ni 2+ ions (Nan et al, 2006) …”

This survey is to review the advancement recorded so far in the lithium-ion battery recycling technologies in compliance with environmental laws. Amongst many of the technologies used to date, the best is the use of simple but scale-up dissolution technology involving non-toxic suitable organic solvents that can effectively dissolve toxic binder, PVdF in battery to avoid much pollution. Pollution through the hydrolysis of LiPF 6 from the lithium-ion battery can also be minimized through conversion to useful compounds instead of using Journal of Environment and Ecology

“…Above all, the hydrometallurgical process is the most well-established technology for recycling valuable metals from LIBs and has many benefits, such as the complete recovery of metals with high purity, low energy consumption, and low gas emission [11][12][13]. Metal species of spent LIBs are typically leached by HCl, HNO 3 , or H 2 SO 4 , with hydrogen peroxide used as a reducing agent in many cases [14][15][16][17]. Most metal species are expected to dissolve with acidic leaching reagents.…”

LiNi x Co y Mn z (NCM), one of the most promising candidates for high-capacity cathode materials in Li-ion batteries (LIBs), is synthesized with various amounts of Sn. Sn-incorporated NCM from the resynthesis of NMC in leach liquor containing Sn from spent LIBs is characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, particle strength tests, and electrochemical tests. Sn-incorporated NCM has a globular form, and the uniform distribution of Sn inside cathode materials is confirmed. As Sn is introduced, the (003) diffraction peak tends to shift to a smaller angle and particle breaking strength increases. It is found that Sn-incorporated cathode active materials have better cycle performance and rate capability than pristine cathode active material although the discharge capacity slightly decreases. Because there is a trade-off between decreased discharge capacity and improved cycling and rate performance, the incorporation of Sn in resynthesized NCM should be carefully designed and conducted.

In order to recover the rare earth elements (REEs) from neodymium permanent magnet scraps, Fe 2 O 3 , B 2 O 3 , and FeO-B 2 O 3 fluxes were designed to extract the REEs. The REEs containing oxides were successfully separated from the Fe-based metals at the temperatures of 1,673, 1,773, and 1,823 K. A mechanism for extraction of REEs has been proposed based mainly on the experimental observations using the flux of FeOÁB 2 O 3 at 1,573 K. Effects of temperature and reaction time were also investigated. The experimental results have shown that increasing temperature and prolonging holding time help the reduction of B 2 O 3 contents in the oxide phase. The FeO-B 2 O 3 fluxes show better extraction efficiency. The purity of rare earth oxide was 98.4 % produced by 2FeOÁB 2 O 3 and the extraction ratios were higher than 99.5 % after the FeO-B 2 O 3 fluxes treatment.
