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.

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.
