Abstract: An electrochemical device includes a first electrode in electrical communication with a first current collector, a second electrode in electrical communication with a second current collector and a crosslinked solid polymer in contact with the first and second electrodes. At least one of the first and second electrodes includes a network of electrically connected particles comprising an electroactive material, and the particles of one electrode exert a repelling force on the other electrode when the first and second electrodes are combined with an uncrosslinked precursor to the solid polymer.

Abstract: The present invention relates generally to electrodes for use in electrochemical devices, and more particularly, to coated electrode particles for use in solid electrochemical cells, and to materials and systems for improving electronic conductivity and repulsive force characteristics of an electrode network. The present invention also relates to an article comprising a plurality of electroactive particles that form an electrode network wherein the electroactive particles are coated with a system of electrically conductive and low refractive index materials.
