HYBRID SODIUM-CARBON DIOXIDE SECONDARY BATTERY CAPABLE OF OBTAINING ENERGY STORAGE ALONG WITH HIGH VALUE-ADDED PRODUCT BY ELECTROCHEMICAL CARBON DIOXIDE REDUCTION AND SECONDARY BATTERY SYSTEM COMPRISING THE SAME

摘要

The present invention relates to a hybrid sodium-carbon secondary battery capable of obtaining a high value-added product through an electrochemical reduction reaction of carbon dioxide as well as energy storage, and a secondary battery complex system including the same, and more particularly, to a hybrid sodium-carbon dioxide of the present invention. A secondary battery contains sodium metal and an organic electrolyte in the negative electrode, and a metal-carbon composite catalyst and an aqueous electrolyte in the positive electrode, so that various kinds of high value-added carbon compounds and electric energy can be obtained simultaneously during discharge. . In addition, since the secondary battery composite system of the present invention includes an energy storage system and the hybrid sodium-carbon dioxide secondary battery, various high value-added carbon compounds and electrical energy can be obtained simultaneously when discharging in one device, and the produced electrical energy is flexible. It has the advantage of efficient use of energy by storing and converting it.
