NOVELTY - The method involves applying an actinic/electron beam radiation cured aqueous mixture (50) to an aluminum electrode current collector (42) to form a layer (44) on the current collector, where the aqueous mixture comprises polymer precursor, solid electrode particles (52) and water and the polymer precursor is dispersed or dissolved in the water. The layer is subjected to electron beam and actinic radiation for polymerizing and crosslinking the polymer precursor to form an electrode binder that binds the solid electrode particles to the current collector and form an electrode.    USE - Method for forming an electrode e.g. cathode electrode and anode electrode, for a battery e.g. lithium ion battery such as cylindrical, prismatic and pouch-type battery, and an electric double layer capacitor (all claimed) of an electrochemical device/cell for auxiliary power supplies for electric vehicles i.e. automobiles. Can also be used for power supplies of portable devices e.g. phones, music players and portable computers, military application and aerospace application.    ADVANTAGE - The method enables forming the electrode to incorporate a relatively short residence time for actinic radiation curing and electron beam curing such that resulting application of the layer to the current collector and crosslinking of the current collector increases production speed and reduces capital and operating costs by eliminating a need for thermal curing ovens and associated energy inefficiencies of thermal drying in lieu of actinic and electron beam radiation curing stations so as to reduce processing time cured electrode binding materials. The method enables functionalizing the polymer precursors with carboxy, amino, and hydroxyl functionality that can increase hydrophilic characteristics of the polymer precursor and improve dispersability of the polymer precursors in the aqueous mixture.    DETAILED DESCRIPTION - The solid electrode particles are selected from a group consisting of carbon particulate materials, silicon-based materials, metal oxide salts and ceramic materials. INDEPENDENT CLAIMS are also included for the following:    (1) an electrode    (2) an electric double layer capacitor    (3) a battery.
