Abstract
An electrode includes a current collector, a metal shell in direct contact with and encapsulating the current collector, green dendritic columnar growths extending out of the metal shell and having protrusions thereon, and active material in contact with the metal shell and having embedded therein the green dendritic columnar growths. The protrusions penetrate the active material to form a mechanical retainer that prevents delamination of the active material from the metal shell and define localized regions of increased current density during operation of the electrode that promote deposition of the active material first on the protrusions and then on areas of the green dendritic columnar growths adjacent to the protrusions such that the active material electrochemically adheres to the green dendritic columnar growths and the protrusions enlarge during repeated charge and discharge cycling of the electrode.
