Boundary-free structure for electrode particles eliminates reactions that diminish battery life.
Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have a long history of breakthrough discoveries with lithium-ion batteries. Many of these discoveries have focused on a battery cathode known as NMC, a nickel-manganese-cobalt oxide. Batteries with this cathode now power the Chevy Bolt.
Argonne researchers have made another breakthrough with the NMC cathode. The team’s new structure for the cathode’s micro-sized particles could lead to longer-lasting and safer batteries able to operate at very high voltage and power vehicles for longer driving ranges.
“We now have guidelines that battery manufacturers can use to prepare cathode material that is boundary-free and works at high voltage.” — Khalil Amine, Argonne Distinguished Fellow
“The…
