Dentrite-suppressed mesoporous structure cathode electrode

This technology is related to metal cathode electrodes and secondary batteries using them.

The problem that this technology aims to solve is a metal cathode electrode with suppressed dendrite growth. To this end, we propose a mesoporous structure in which the surface area is increased by nanopores on the inner surface of the concave part.

This technology not only inhibits the growth of lithium ions into lithium metal dendrites by nanopores and oxygen functional groups, but also suppresses the generation of by-products within the cathode electrode, and the effect of this is to prevent long-term charge and discharge cycles. It has outstanding advantages of high efficiency and stability.

Key Features:

• Among the concave and convex portions of the metal substrate structure, selectively form nanopores and oxygen functional groups within the concave portion
• Make the inner surface of the concave portion lithiophilic and provide an oxidizing solution to the metal substrate structure
• Provide a mask on the convex portion of the metal substrate structure
• The inner surface of the concave portion has a mesoporous structure by nanopores have
