NOVELTY - The assembly (100) has a separation layer fixed between a positive electrode (110) and a negative electrode (120) that are integrated with each other. The separation layer is provided with a multi-layer structure that is provided with multiple two-phase electrolytes (140). Each two-phase electrolyte is made of a liquid component and a polymer matrix. Multiple three-phase electrolytes (130) are made of a liquid component, a solid component and a polymer matrix. The polymer matrices of the separation layer are connected to the positive electrode and the negative electrode.    USE - Electrode assembly for a lithium secondary battery of a battery module in a battery pack that is utilized as a power source in a medium-to large-sized device such as electric vehicle, hybrid electric vehicle, plug-in hybrid electric vehicle e.g. electric-bike and electric-scooter and power storage system (allclaimed) and electricity two-wheeled vehicle i.e. electrical golf cart.    ADVANTAGE - The assembly prevents short circuit caused by contraction of a separation film, improves ion conductivity of an electrode, long-term performance and retention property of a battery, progresses battery characteristic evaluation without a separate impregnation process and increases electrode dispersion dust process time by dipping the electrolyte at an electrode during manufacturing process.    DETAILED DESCRIPTION - Each electrolyte is made of ethylene carbonate, polypropylene carbonate, butylene carbonate, vinylenecarbonate, di-ethyl carbonate, dimethyl carbonate, ethyl methyl carbonate, gamma-butyrolactone, sulfolane, methyl acetate and methylpropio nay trough. Polyoxide based non-bridging polymer is ethylene oxide, propylene oxide, oxymethylene and dimethylsiloxane. A non-bridging polymer is polyacrylonitrile, methyl methacrylate, vinyl chloride, vinylidene fluoride, vinylidenefluoride-co-hexafluoropropylene, ethylene imine and p-phenylene terephthalamide. A monomer is trimethylolpropane ethoxylate triacylate, polyethylene glycol di-methacrylate, polyethylene glycolarylate, divinylbenzene, polyester dimethacrylate, divinyl ether, trimethylolpropane, trimethylolpropane trimethacrylate and ethoxylated bisphenol dimethacrylate. An INDEPENDENT CLAIM is also included for an electrode assembly manufacturing method.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a electrode assembly.
