[SMM New Energy News Flash] Recycling lithium-ion batteries is complex, costly, and often results in batteries ending up in landfills. To address this, MIT researchers developed a sustainable electrolyte made from aramid amphiphiles (AAs) and polyethylene glycol (PEG). This material forms robust nanoribbons in water and dissolves easily in organic solvents, enabling easier recycling without toxic, flammable, or costly chemicals. While the new electrolyte is not yet as efficient as commercial options due to ion polarization, it demonstrates a proof of concept for more sustainable battery recycling. Researchers envision its use as part of a layered electrolyte system, potentially reducing recycling costs, environmental impacts, and reliance on destructive lithium mining.
