New Argonne coating could have big implications for lithium batteries

15.05.2019 | Argonne National Laboratory | www.anl.gov

Building a better lithium-ion battery involves addressing a myriad of factors simultaneously, from keeping the battery’s cathode electrically and ionically conductive to making sure that the battery stays safe after many cycles.

In a new discovery, scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed a new cathode coating by using an oxidative chemical vapor deposition technique that can help solve these and several other potential issues with lithium-ion batteries all in one stroke.

Argonne coating

Unlike conventional coatings, which only protect the exterior surface of the micron-sized cathode particles and leave the interior vulnerable to cracking, new coating had the ability to penetrate to the cathode particle’s interior, adding an additional layer of shielding.
