Scalable Technique Produces New Battery Cathodes Using 92% Recycled Materials

In a major step forward for sustainable energy technology, researchers at Worcester Polytechnic Institute (WPI), led by Professor Yan Wang, William B. Smith Professor of Mechanical and Materials Engineering, have developed a new, scalable method to recycle lithium-ion batteries in a way that is both efficient and environmentally friendly.
The team’s research, titled Upcycling Mixed Spent Ni-Lean Cathodes into Ni-Rich Polycrystalline Cathodes, was recently published in Energy Storage Materials, a multidisciplinary peer-reviewed journal focused on the topics of materials and energy. The paper details an innovative hydrometallurgical upcycling approach that offers both environmental and performance advantages over traditional recycling methods.
