TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Method: An electrode mixture layer with electrode active material is formed on an electrode collector in electrode(s) of a belt-shaped positive or negative electrode.Terminal is attached to the electrode collector exposed region where the electrode mixture layer is unformed.The electrode collector between the electrode mixture layer is cut.A protection tape is disposed on the terminal after the terminal is attached to the electrode collector exposed region.The electrode mixture layers are formed at regions on the surface and back of the electrode collector. The electrolyte layer is formed by pushing electrolyte with an electrolyte-delivering machine having a pressurizer.The electrolyte is delivered while being heated to adjust its viscosity to 0.001-0.05 Pa-s.The electrode is rolled after delivering and drying the electrolyte.Preferred Component: The electrolyte includes electrolyte salts, macromolecular compounds, and non-aqueous solvents.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Materials: The electrolyte salts include LiPF6, LiAsF6, LiBF4, LiClO4, LiCF3SO3, Li(CF3SO2)2N, and/or LiC4F9SO3.
