Abstract
An electrode component for an electrochemical cell is provided herein. The electrode component includes a current collector having a first surface, a metal oxide layer disposed on the first surface of the current collector, and a lithium-containing layer bonded to the first surface of the current collector. The metal oxide layer includes a plurality of features. A method for manufacturing such an electrode component is also provided herein. The method includes directing a laser beam toward the first surface of the current collector in the presence of oxygen to form the metal oxide layer on the first surface and applying the lithium-containing layer to the metal oxide layer thereby bonding the lithium-containing layer with the current collector.
