A team led by researchers from Argonne National Laboratory has identified a fundamental source of instability in nickel-manganese-cobalt oxide (NMC) cathodes: the domain boundaries that are present in single-crystalline cathode particles. The researchers also devised a method for producing boundary-free single crystals to improve NMC performance. A paper on the...
A new structure has been created for the cathode’s micro-sized particles, leading to safer and longer-lasting batteries capable of working at high voltage and power vehicles to cover greater driving distances.
Boundary-free structure for electrode particles eliminates reactions that diminish battery life.
The First International Conference on Heterostructured Materials (HSM I) was held from 12 to 15 July 2022. This hybrid event was hosted by Hong Kong Institute for Advanced Study (HKIAS) and co-organized by Shenyang National Laboratory for Materials Science, China. The 4-day conference was well-attended by scholars and scientists from worldwide.
Researchers have uncovered a new avenue for overcoming the performance decline that occurs with repeated cycling in the cathodes of next-generation batteries. This discovery could find applications in batteries for transportation and the electric grid.
