Abstract
Protective layers in lithium-ion electrochemical cells, and associated electrodes and methods, are generally described. The protective layers may comprise lithium-ion-conductive inorganic ceramic materials, such as lithium oxide, lithium nitride, and/or lithium oxysulfide. The resulting lithium-ion electrochemical cells may exhibit enhanced performance, including reduced capacity fade rates and reduced self-discharge rates.
