A lithium metal electrode and its related lithium metal battery is disclosed in the present invention. The lithium metal electrode comprises a current collector, a lithium metal layer, an insulation frame, a porous electrical insulation layer and an ionic diffusion layer. The current collector has at least a well. The lithium metal layer is disposed on the bottom surface of the well. The insulation frame is disposed alone the opening of the well. The insulation frame extends radially outward the opening to cover a top surface of the current collector partially and extends vertically toward the inner sidewall of the well. The lithium dendrites will mostly plate in the well and will not plate upwards due to the inhibition layer. Hence, the lithium dendrites will not penetrate through the electrical insulator so that the safety of the lithium metal battery can be improved greatly.
Claudiu B. Bucur obtained his Ph.D. in 2008 from Florida State University under the mentorship of distinguished Leo Mandelkern Professor of Polymer Science, Joseph B. Schlenoff. He studied the manner in which polyelectrolyte multilayers assemble, and how doping them with ions changes their mechanical and thermodynamic properties. In 2010 he completed his postdoctoral studies at the USDA Agricultural Research Service Labs, where he investigated corrosion inhibition via biomembranes. Dr. Bucur then joined the Post Lithium Ion Research Group at the Toyota Research Institute of North America, where he focused on metallic anodes such as magnesium, lithium, sodium, and their electrolytes as well as high capacity conversion cathodes such as the sulfur cathode. He expanded upon his experience with polymers, corrosion, and interfaces and was able to advance many areas in the battery field. Currently, Dr. Bucur is Chief Engineer for new battery and solid electrolyte projects at Great Wall Motor, the largest SUV manufacturer in China. He is fascinated by energy storage and dreams of creating the ultimate battery.
