Abstract
Materials and methods for coating an electrochemically active electrode material for use in a lithium-ion battery are provided. In one example, an electrochemically active electrode material comprises: a polymer coating applied directly to an exterior surface of the electrochemically active electrode material; a metal plating catalyst adhered to the continuous polymer; and a continuous metal coating that completely covers the metal catalyst and continuous polymer coating. The electrochemically active electrode material may comprise a powder comprising one or more secondary particles, and the polymer and metal coatings may be applied to exterior surfaces of these secondary particles.
