“…[1][2][3][4] Bacteria from the Sphaerotilus-Leptothrix group participate in biogeochemical rotation of the iron that occurs in the lithosphere. It is a fundamental geological process of iron oxidation performed by microorganisms 5 where, firstly iron is mobilized, then it is used and assimilated by the microbes and finally it is immobilized and deposited.…”

Abstract. Biogenic iron oxides could find application in catalysis but their structure and composition should be well characterized. The content of organic rests due to their origin should also be controlled. Samples of natural biomass and biomass obtained after cultivation in Adler's medium of the SphaerotilusLeptothrix group of bacteria were treated by different techniques to reduce or totally remove the organic residues. The aim of the study was to find procedures, which prevent changes in the oxidation state of the iron and of the type of iron-containing compound(s) during treatment. Mössbauer spectroscopy, IRS, DTA, and SEM were used in the study. Chemical treatment with H 2 O 2 or NaOH at room temperature did not significantly change the samples. Thermal treatment in oxidative flow mixture conducted up to 250 °C resulted in a transformation of the iron-containing phases only. The organic matter, which is included in the structure of the particles, cannot easily be affected. DTA revealed that removal of organic rests occurred in the interval of 250-600 °C. However, the transformation of the initial compounds could not be prevented using such a treatment.

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

“…Most research being done in the recycling of lithium-ion batteries uses cells with LiCoO 2 as the cathode active material and focuses on the recovery of cobalt and lithium [15][16][17][18][19][20], with little attention to the copper and aluminum within the cells. The methods used incorporate various acid leaching and hydro-and pyrometallurgical processes [16][17][18][19] and bioleaching techniques [20].…”

The purpose of this project was to develop and validate a common process for separating the active materials from the copper and aluminum foils of post-vehicleapplication lithium-ion batteries. Batteries from two different manufacturers were disassembled, and anode and cathode samples were used for recycling testing. The materials tested from a third manufacturer were scraps of coated foils from the manufacturing process that had never been assembled into cells. The cathodes from each manufacturer were aluminum foils with coatings of differing chemistries. The anode foils from each manufacturer were copper with a carbon coating. The process developed used acid baths to separate the active materials from the foils. To allow for separation of the differing active materials (depending on supplier and battery chemistry) from the foils, the acids were selected to react with the aluminum and copper foils. The processes were stopped once sufficient reaction had occurred so that the coatings no longer adhered to the foils. The optimum recycling condition was identified as the lowest acid concentration, the lowest temperature, and the shortest time required for full separation of the coatings from the foils for all cell chemistries (manufacturers). Full separation of the graphite coating from the copper foils of the anodes was achieved within 35 s by using 0.5 mol/L of H 2 SO 4 (sulfuric acid) at 40°C. Full separation of the active materials from the aluminum foils of the cathodes was achieved within 83 s by using 2.0 mol/L of HNO 3 (nitric acid) at 70°C.
