Formation of lithium-driven active/inactive nanocomposite electrodes based on Ca₃Co₄O₉ nanoplates

(Figure Presented) A new electrode material that is expected to have promising applications in energy storage and energy-harvesting systems is presented. In this material, which consists of Ca₃Co ₄O₉ nanoplates with a high theoretical gravimetric capacity, the lithium-driven conversion process results in the formation of active/inactive nanocomposite electrodes that mitigate the aggregation of the active nanometals (see picture).
