A brand new examine reveals that lithium—a vital ingredient utilized in rechargeable batteries and vulnerable to produce chain disruption—might be recovered from battery waste utilizing an electrochemically pushed restoration course of. The strategy has been examined on generally used forms of lithium-containing batteries and demonstrates financial viability with the potential to simplify operations, reduce prices and enhance the sustainability and attractiveness of the restoration course of for business use.
The examine, led by College of Illinois Urbana-Champaign chemical and biomolecular engineering professor Xiao Su, describes a course of that leaches metals from batteries into an natural solvent, then makes use of an electrochemical cell during which a polymer-coated electrode is used to seize lithium.
“The main challenge is the presence of other metals in lithium recovery streams, particularly in organic leachates, which is a common way to dissolve spent batteries for recycling,” Su stated. “To overcome these challenges, we’ve introduced a copolymer that captures lithium selectively directly from organic solvents and that can be electrochemically regenerated.”
The examine findings are revealed within the journal ACS Power Letters and have been co-led by former graduate scholar Nayeong Kim, with contributions from postdoctoral researchers Johannes…
