Abstract: A solid-state lithium-based battery having fast charging and recharging speeds (above 3 C) is provided by including a nitrogen-enriched lithiated cathode material surface layer between the lithiated cathode material layer and the lithium-based solid-state electrolyte layer. The nitrogen-enriched lithiated cathode material surface layer can be formed by introducing nitrogen into a lithiated cathode material. The nitrogen can be introduced during the final stage of a deposition process or by utilizing a different process, such as, for example, thermal nitridation, than a deposition process.

Abstract: A solid-state lithium-based battery is provided in which the formation of lithium islands (i.e., lumps) during a charging/recharging cycle is reduced, or even eliminated. Reduction or elimination of lithium islands (i.e., lumps) can be provided by forming a lithium nucleation enhancement liner between a lithium-based solid-state electrolyte layer and a top electrode of a solid-state lithium based battery.
