Hydrometallurgical Treatment

The paper reports investigations of the direct recovery of copper and cobalt from sulphate solution after leaching of spent Li-ion cells. Metals of high purity (above 99%) can be selectively obtained if the electrolysis process is carried out at proper pH: 1 for Cu and 4 for Co. During cobalt electrowinning, the oxidation of Co(II) ions and formation of Co(III) compounds on the anode were observed. Lithium ions accumulated mainly in the electrolyte. Application of ammoniacal solution for selective lithium carbonate precipitation in the presence of cobalt ions was not effective due to high temperature of the process and no possible formation of the stable and soluble cobalt-ammonia complexes.

In this article, the structure and morphology of the carbon anode materials with different dimensions have been characterized through SEM and TEM. The performances of electrochemical intercalation and deintercalation of lithium-ions have been studied. The results show that graphene as the two dimensional nanomaterials possess more advantages of microstructure and better Li-ions intercalation performances than carbon nanotubes (CNTs) and graphite. The superior abilities of Li-ions intercalation and deintercalation are attributed to increasing lithium storage space, decreasing Li diffusion distance, and higher specific surface area for Li-ions.

This paper is a product purity study of recycled Li-ion batteries with a focus on hydrometallurgical recycling processes. Firstly, a brief description of the current recycling status was presented based on the research data. Moreover, this work presented the influence of impurities such as Cu, Fe and Mg on recovered cathode materials performance. The impact of the impurities was described depending on their form (metallic or ionic) and concentration. This work also reviewed hydrometallurgical recycling processes depending on the recovered material, obtained purity and recovery methods. This purity data were obtained from both research and battery industry actors. Finally, the purity study was completed by collecting data regarding commercial battery-grade chemical compounds and active lithium cathode materials, including required purity levels and allowed impurity limitations.

Spinel LiMn2O4 nanorods were prepared by a hydrothermal method followed by solid-state lithiation. The produce β-MnO2 nanowire as template, and LiOH·H2O was used as lithium source. The spinel LiMn2O4 nanorods samples were characterized by SEM, XRD, (HR)TEM, and galvanostatic charge/discharge profile measurement. Compared with the LiMn2O4 nanoparticles, the LiMn2O4 nanorods showed superior cycling stability, better rate capability, good high temperature performance, and delivered a discharge capacity of 122 mAh/g (at 1 C, 100 cycles).
