New Coating could have Big Implications for Lithium Batteries

Argonne scientists have developed a new coating (shown in blue) for battery cathodes that can improve the electronic and ionic conductivity of a battery while improving its safety and cycling performance. (Image by Argonne National Laboratory.)

Coating provides extra layer of protection for battery cathodes. Scientists have developed a new cathode coating by using an oxidative chemical vapor deposition technique. It can keep a battery’s cathode electrically and ionically conductive and ensures that the battery stays safe after many cycles. “The coating we’ve discovered really hits five or six birds with one stone.” Khalil Amine, Argonne distinguished fellow and battery scientist.

In the research, Amine and his fellow researchers took particles of Argonne’s pioneering nickel-mangan...
