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 Ca 3 Co 4 O 9 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).
