Anode for an Aqueous Zinc Battery Coated with MOF (Metal-Organic Framework)-801 and Aqueous Zinc Battery Including the Same

MOF-801-Coated Aqueous Zinc Battery Anode Technology

This technology relates to an aqueous zinc battery anode and separator employing an MOF-801-based porous coating layer to improve ion-selective transport characteristics.

Conventional aqueous zinc batteries have suffered from vanadium oxide ion dissolution and zinc dendrite growth, which reduce lifespan and stability. This technology forms an MOF-801 coating layer having pores of 4.3 Å to 8.34 Å so that Zn2+ ions selectively pass while transport of VO2+ is suppressed.

As a result, it can reduce dendrite formation and corrosion while improving structural stability and capacity retention, making it advantageous for long-life aqueous zinc batteries.

Key Features:

• It forms a porous coating layer including MOF-801 metal-organic particles on the anode and separator surfaces.
• It simultaneously realizes selective Zn2+ transport and blocking of vanadium oxide ions.
• It is advantageous for suppressing zinc dendrite growth and reducing electrode corrosion.
• It can be manufactured through doctor-blading or drop-casting processes.
