Faster battery recycling using ultrasound
As the electrification of society increases, so does the amount of used batteries that need to be recycled. Researchers at KTH have developed a new method to recycle valuable metals from used lithium batteries.
Is it possible to extract metals from a lithium battery in half the time it normally takes? Is it possible to use acids that are common in most homes worldwide for the extraction process? The answer is yes. Researchers at CBH have discovered a way.
In a scientific article published by the journal Green Chemistry, Xiong Xiao, a postdoc at the Division of Polymeric Materials at KTH, explains how it works using ultrasound.
“We perform the metal extraction in half the time it normally takes and we take out more metal ion than normally reported in scientific literature. In the extraction process we use mild acids such as acetic acid and citric acid instead of sulfuric acid, which is very beneficial from a work environment and sustainable development point of view,” says Xiong Xiao.
