Recovery of lithium (Li) from lithium-ion battery (LIB) wastewater is critical due to the increasing application of LIBs. In this study, we developed a novel membrane-based process to recover Li in crystalline form from LIB wastewater.
What is lithium-ion battery (LIB) production wastewater?
Lithium-ion battery (LIB) production wastewater boasts elevated organic content, our pilot wastewater treatment module integrated with Boron-doped diamond BDD electrode could degrade refractory organic pollutants to extremely low concentrations, which secure effluent discharge and enhanced traceability & sustainability .
Can We valorize battery manufacturing wastewater characterized by high salt concentrations?
In this study, we demonstrate a practical approach for valorizing battery manufacturing wastewater, characterized by high salt concentrations. This approach overcomes the osmotic pressure limitation while ensuring high overall yield and purity.
Can NF-MDC process recover lithium in crystalline form from lithium-ion battery wastewater?
NF-MDC process achieves high-purity lithium crystals without any post-treatment. Recovery of lithium (Li) from lithium-ion battery (LIB) wastewater is critical due to the increasing application of LIBs. In this study, we developed a novel membrane-based process to recover Li in crystalline form from LIB wastewater.
What ions are recovered from battery manufacturing wastewater?
Transition metal ions (Ni 2+, Cu 2+, and Cd 2+) are recovered by 90 % from wastewater. Transition metal ions are enriched to a 43-fold concentration, achieving 99.8% purity. Leveraging the latent value within battery manufacturing wastewater holds considerable potential for promoting the sustainability of the water-energy nexus.
How can lithium-ion batteries be manufactured?
Lithium-ion batteries (LIBs) need to be manufactured at speed and scale for their use in electric vehicles and devices. However, LIB electrode manufacturing via conventional wet slurry processing is energy-intensive and costly, challenging the goal to achieve sustainable, affordable and facile manufacturing of high-performance LIBs.
Why are lithium-ion batteries important?
Lithium-ion batteries serve as the catalyst for energy storage, leading the charge in the eco-conscious movement across diverse sectors and bolstering our shared dedication to a greener tomorrow.
