Adsorptive removal of aqueous MB molecules by spent lithium-ion battery cathode scrap

Chemical Engineering Communications, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 13

Published: Jan. 27, 2025

This study describes the application of cathode scrap obtained from spent lithium-ion batteries (LIBs) in adsorptive removal aqueous MB dye molecules. The physicochemical properties are thoroughly examined. High-resolution microscopic images display aggregation small-sized particles scrap. Thermogravimetric analysis confirms presence stable metallic compounds (89% by weight) above 600 °C. Surface charge proves that negative surface increases with rising pH solution. high facilitates adsorption positively charged molecules onto negatively maximum quantity adsorbed, as determined Langmuir model, is 80.42 mg/g at 12. Further, material may be regenerated efficiently post-adsorption without requiring any expensive solvent. Reusability studies demonstrate maintains its activity even after five test cycles. slight reduction observed each cycle attributed to loss some active sites into solution during repeated use. data clearly confirm has potential remove various pollutants wastewater proper optimization pretreatment conditions.

A novel in situ detection method for lithium plating thickness in pouch cell

Physics of Fluids, Journal Year: 2025, Volume and Issue: 37(2)

Published: Feb. 1, 2025

Lithium plating on the surface of anode electrodes poses significant hazards to cell performance. deposition not only leads thickness growth and swelling but also promotes formation lithium dendrites, which can penetrate cell's separator. However, changes serve as an accurate indicator for detecting in cells. This study aims precisely monitor state by tracking changes. An experimental situ with a resolution 0.1 μm is developed detect without requiring disassembly during normal operation. A cobalt oxide pouch then tested under various ambient temperatures charging rates using this setup. The precise conditions plating, including specific temperature, charge, voltage, capacity, are identified. Furthermore, multi-physics coupled equation system dendrite proposed align conditions. results demonstrate that higher currents accelerate due increased polarization, window charge rate 1C (SOC) = 16%. Additionally, dendrites more likely form high-rate at low temperatures, approximately 5% ions contributing formation, temperature 0 °C SOC 27%. In summary, detection valid method unveiling inside battery.
