NOVELTY - The method involves combining a cathode with stable polymeric organic radical-based material in a slurry cast, where the cathode comprises radical PMMA combinations and non-PMMA radical combinations. The cathode is deposited on a substrate. An electrolyte is deposited on the cathode. An anode is deposited on cathode-electrolyte layers. The electrolyte is selected from one of solid-state polymer, ionic liquid, solvent based electrolyte and gel. The anode is selected from one of metallic magnesium, magnesium compounds, magnesium-doped carbon and boron doped magnesium.    USE - Method for making an electrochemical energy storage device such as energy storage/discharge device i.e. lithium-ion battery, and electrochromic device i.e. smart window, in different applications such as portable consumer electronic devices, electrical grids, electric vehicles i.e. automobile, and operating devices e.g. implantable medical devices, remote sensors, miniature transmitters, smart cards, and microelectronic devices. Can also be used for military and aerospace applications.    ADVANTAGE - The method ensures that an organic radical battery (ORB) with thousand deep charging and discharging cycles is operated at high rates/loads at full utilization of capacity without performance loss. The method enables utilizing the SWNTs act as a binder so as to improve electrode structural integrity due to dispersion efficiency and effective percolation when utilization rate of current collectors of the SWNTs can be minimized. The method enables improving ionic conductivity and electrochemical potential window stability feasible prior to attempted integration with novel cathode and anode materials.    DETAILED DESCRIPTION - The anode is selected from one of nanostructured carbon of single-wall nanotubes (SWNTs), double-wall nanotubes, multi-wall nanotubes, carbon fibers, fullerenes, graphenes and micro-beads.    DESCRIPTION OF DRAWING(S) - The drawing shows a circuit diagram of an electrochemical device.
