Illinois Engineers Patent Game-Changing Battery Recycling Method
A groundbreaking battery recycling method has been patented by Illinois Grainger engineers. The single-step process, developed by Jie Wang, Xinyang Mao, and Xiulin Fan, recovers and repurposes metals from old battery cathodes, significantly reducing costs and environmental impact.
The new technique dissolves materials from spent cathodes, specifically lithium cobalt oxide, the most common in phone and laptop batteries. It then deposits these onto new cathodes in a single electrochemical process. This one-step process is eight times cheaper and halves the environmental impact of traditional recycling methods.
The study, published in the latest news today, shows the new method outperforms current techniques in economic efficiency, environmental impact, resource impact, and human health risk. The researchers plan to extend this technology to other cathode chemistries, further expanding its potential.
The international patent filing for this innovative battery recycling method marks a significant step forward in sustainable battery production. By recovering and repurposing materials in a single, affordable, and eco-friendly process, this technology could revolutionize the battery market.
