2,590 cycles: WPI turns mixed battery waste into new cells
Researchers at Worcester Polytechnic Institute built full test cells from recovered waste that lasted about twice as long as commercial ones.
Scientists took apart old batteries and used the pieces to make new ones. The new ones lasted about twice as long in tests. It is still a lab idea.

Your call: hype or real?
Real = it will matter in daily use. Hype = louder than it is. One vote, and it can’t be changed.
Our view and readers’ views are opinions, not statements of fact about a product.
Why it matters
Old batteries could become new ones without losing quality. This is lab work, so it is years from products.
Worth a look: old batteries may get a second life.
The details
- A team led by Prof. Yan Wang made a cathode and a graphite anode from recovered battery waste.
- Pouch cells built only from these materials kept 70% of capacity after 2,590 cycles.
- Cycle life was about double that of cells made with commercial materials.
- The team's analysis says over 95% of waste could be used, with 27% lower greenhouse gases than a reference route.
- The results are from the lab; the article names no partners or timeline. Published in Advanced Energy Materials.
