Efficient recovery of lithium as Li2CO3 and cobalt as Co3O4 from spent lithium-ion batteries after leaching with p-toluene sulfonic acid
Get PDFRechargeable lithium-ion batteries (LIBs) have been widely used in consumer electronics and electric vehicles. In terms of environmental restrictions and circular economy, proper treatment of spent LIBs is of great significance for achieving sustainable development. In this study, organic p-toluene sulfonic acid (PTSA) was employed to recycle valuable Li and Co elements from the spent LIBs for production of battery raw materials (e.g. Li2CO3 and Co3O4). Operation parameters such as PTSA concentration, hydrogen peroxide (H2O2) concentration, solid-toliquid ratio, leaching temperature and leaching time, were systematically investigated. Under the optimal conditions (0.9 vol% H2O2, 1.5 mol L 1 PTSA, 30 g L 1 solid-to-liquid ratio, 80 ◦C, and 60 min), the leaching efficiencies of commercial LiCoO2 could reach ~100% and 99% for Li and Co, respectively, while the corresponding values were about 95% and 93% for the spent LiCoO2. In addition, the selective precipitation of Co-rich compounds in cooled leachate allowed an effective separation of Co from the mixture. The high recovery yield of Co3O4 and Li2CO3 demonstrated the great potential of the PTSA-assisted leaching strategy in hydrometallurgical recycling of the spent LIBs for practical applications. Overall, this proposed recovery process is simple, efficient, and environmentally friendly and is of vital importance for rational treatment of spent LIBs
Investigation of the electrocatalytic mechanisms of urea oxidation reaction on the surface of transition metal oxides
Get PDFUrea oxidation reaction (UOR) has been widely considered as an alternative anodic reaction to water oxidation for the green production of hydrogen fuel. Due to the high catalytic activity of transition metal oxides towards UOR, various strategies have been developed to improve their syntheses and catalytic properties. However, little is known about the underlying mechanisms of UOR on catalyst surface. In this work, three transition metal oxides, including NiO, Co3O4, and Fe2O3 are investigated as model catalysts. Through analyzing the electrochemical properties by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and operando Raman spectroscopy, it is revealed that NiO has a unique high catalytic activity towards UOR due to simultaneous formation of a thin layer of oxyhydroxide species above 1.40 V vs. RHE in alkaline media. In addition, density functional theory (DFT) calculations further suggest that the adsorption of urea molecules is largely affected by surface interactions resulting in different space configurations, which impose large influences on the consecutive deprotonation and NAN formation processes. Overall, results of this work point to the subtle adsorption- kinetics relationship in UOR and highlight the importance of the interfacial electronic interactions on catalyst surface
