Abstract
The present disclosure provides an electrochemical cell that includes an electrically conductive material layer, a precursor material disposed on or adjacent to a first surface of the electrically conductive material layer, and an electroactive material layer disposed on or adjacent to the precursor material. In certain variations, the precursor material forms a continuous layer and a solid-electrolyte interface layer is disposed on or adjacent to an exposed surface of the electroactive material layer. In other variations, the precursor material forms a plurality of distinct precursor structures disposed on the first surface of the electrically conductive material layer in a predetermined pattern, such that at least a portion of each distinct precursor structure is unobstructed by the electroactive material layer. The distinct precursor structures are configured to form surface structures that chemically attach the solid-electrolyte interface layer and the electrically conductive material layer.
