The separation of electrode active materials from spent Li-ion batteries (LIBs) by froth flotation is challenging due to the changes in surface properties cycling as well presence organic binders. In this work, aged anode and cathode composite LIBs was systematically investigated after were heat treated. results show that can be separated each other a heating process air at 400 °C which some PVDF binder remains intact. underlying mechanism X-ray photoelectron spectroscopy (XPS), contact...
Separation between two recycled electrode active materials from spent Li-ion batteries by a conventional froth flotation method has been challenging due to similarity in their surface hydrophobicity. In this study, new coarse flake particle technology developed separate the batteries. The process separates particles effectively at size range of 212–850 μm taking advantage significant difference densities anode and cathode materials. At feed 212 or less, fraction is floated layers resulting...
With the rapid growth of volume spent Li-ion batteries (LIBs), recycling LIBs has attracted significant attention in recent years for future sustainability. In particular, there remains a great need development scalable and environment-friendly separation process to recycle valuable cathode active materials from electrode scraps. this work, froth flotation technique was adopted separate mixture anode materials. To evaluate whether recovered maintain their functional integrity after developed...
We examine the fake news phenomenon from a fresh perspective. Instead of assessing factuality claims, our work explores impact these claims on reader beliefs. With 2017 Alabama senate race as empirical context, we how readers both sides political spectrum evaluate online stories considering their preconceived beliefs and values. Our analysis builds concepts argument social representations theories to explore role argumentation in this process. focus detecting arguments comments depict...
Direct recycling of Li-ion batteries is a promising and low-cost technology since the process recovers values active materials directly without converting into metal elements. However, challenging from separation perspective due to purity requirement. Herein, new physical system was developed recycle produce ultra-high cathode EV batteries. Results showed that recycled material product contained 99% with less than 500 ppm aluminum copper. Both stoichimetry structure remained same compared...
The increasing demand for Li-ion batteries (LIBs) in hybrid and electric vehicles had led to a significant increase the volume of new end-of-life LIBs. For this reason, recycling spent LIBs has attracted attention recent years future sustainability. Different from existing methods such as pyrometallurgical hydrometallurgical methods, direct method recovers cathode anode active materials directly reusable forms at low cost. This process consists two steps: 1) liberation separation, 2)...
