CATALYST SYSTEM BASED ON PORPHYRINS INCLUDING DIFFERENT CENTER METALS, CATHODE OF LITHIUM BATTERY USING THE PORPHYRIN BASED CATALYST SYSTEM, AND LITHIUM BATTERY INCLUDING THE CATHODE OF LITHIUM BATTERY

摘要

Disclosed are a catalyst system based on porphyrins of different central metals, a positive electrode for a lithium battery using the catalyst system, and a lithium battery including the positive electrode for a lithium battery. The catalyst system according to an embodiment includes a first porphyrin-based catalyst in which a central metal of porphyrin is substituted with a first metal selected from a predetermined metal group, and a first metal selected from a predetermined metal group by replacing the central metal of the porphyrin with a first metal selected from a predetermined metal group; may include a second porphyrin-based catalyst substituted with another second metal.
