Abstract

A composite electrode for an electrochemical cell that cycles lithium ions may include a metal current collector having a three-dimensional porous structure defining an interconnected network of open pores and an electrode material disposed within the open pores of the current collector. An oxygen-containing reactive layer may be formed on surfaces of the current collector and an electrode precursor mixture may be deposited thereon and dried to form a solid electrode material having a continuous structure within the open pores of the current collector. The electroactive material particles and/or the electrically conductive agent may interact with the oxygen-containing reactive layer on the metal current collector to form an oxygen-containing adhesive layer along an interface between the current collector and the solid electrode material. The electroactive material particles and the electrically conductive agent may be chemically bonded to the current collector via hydrogen bonds within the oxygen-containing adhesive layer.
