The number of lithium-ion batteries (LIBs) is steadily increasing in order to meet the ever-growing demand for sustainable energy and a high quality life humankind. At same time, resulting large LIB waste certainly poses safety hazards if it not properly disposed will seriously harm environment due its inherent toxicity use toxic substances. Moreover, consumption many scarce precious metal reso...

With the global demand for economically important metals increasing, compounded by depletion of readily accessible ores, secondary resources and low-grade ores are being targeted to meet growing demands. Novel technologies developed within biobased industries, such as microbial biosurfactants, could be implemented improve sustainability traditional hydrometallurgy techniques. This study investi...

Abstract The recycling of spent batteries has become increasingly important owing to their wide applications, abundant raw material supply, and sustainable development. Compared with the degraded cathode, anode graphite often a relatively intact structure few defects after long cycling. Yet, most is simply burned or discarded due its limited value inferior performance on using conventional meth...

Due to the accumulation of waste mobile devices, increasing production electric vehicles, and development stationary energy storage systems, recycling end-of-life Li-ion batteries (EOL LIBs) has recently become an intensively emerging research field. The number LIBs produced accelerates resources’ depletion provokes pollution. To prevent this, global communities are concerned with expanding imp...

Research on the regeneration of cathode materials spent lithium-ion batteries for resource reclamation and environmental protection is attracting more attention today. However, majority studies recycling (LIBs) placed emphasis only recovering target metals, such as Co, Ni, Li, from materials, or how to recycle LIBs by conventional means. Effective strategies (e.g., pyrometallurgical technologie...

Acid leaching is an essential unit in hydrometallurgy, yet it time consuming and requires concentrated acids. Process intensification examined for the of valuable rare earth elements (REEs), such as Ni, Co, La, Nd, Ce, from spent nickel metal hydride (NiMH) batteries using subcritical water extraction (SWE) microwave-assisted (MAE). Results SWE revealed that HCl performed better than H2SO4 HNO3...

High-alumina coal fly ash (HAFA: 45% Al2O3 and 40% SiO2) is regarded as a special solid waste that generated from power plants in northwestern China. It an important substitute for bauxite applied to prepare mullite-based ceramics. In this work, hydrometallurgy–pyrometallurgy synergistic process proposed resolve the lower Al2O3/SiO2 mass ratio (Al/Si) degree of crystallinity can promote formati...

Abstract. The demand for lithium (Li) resources is soaring due to the widespread production (or consumption) of electronic products such as mobile and devices, laptops, tablets, home-appliances goods in accommodating current global lifestyle). other lithium-ion batteries (LiBs) applications include electric vehicles, solar panels, wind turbines, toys. increasing Li, while driving economic progr...

By-products from zinc hydrometallurgy are classified as hazardous waste with strong leaching toxicities. Even though numerous research papers dedicated to valorizing valuable metals in it, the primary management route is still disposal or partial reuse, such Waelz process. Presented experimental investigates possibilities of sulfidization and further processing a technologically sustainable for...
