DID YOU KNOW
Did you know that a UC San Diego assistant professor says he has developed a sustainable and effective way to recycle lithium-ion batteries that have already reached their maximum number of charging cycles? As a solution to the short battery life problem that most mobile phone users have, 31-year-old UC San Diego nanoengineer Zhang Chen has found a way to recycle the lithium batteries of his six cellphones and five laptops. In his lab in the university, Chen and his colleagues were able to remove particles from a used battery, heat it up with a solution with lithium salt, and then put them into new batteries. According to his study, the new batteries have the same cycle and life with the old one. His team is still finding out ways to transform the process into an industrial scale, which if successful will definitely help reduce the cost of producing lithium-ion batteries, both financially and environmentally. Batteries are less harmful to the environment than burning oil and coal but its production takes a large toll, especially in areas where it is produced. In the so-called lithium triangle of Argentina, Chile, and Bolivia, where lithium is produced in its brine sites, the locals are afraid that the process will worsen the drought on water since producing one ton of lithium takes about half a million gallons of water. If Chen succeeds in making this process sustainable on an industrial scale, it will also reduce the cost of making battery-dependent products from Samsung and Panasonic.
