    摘要: First and second coaters, first and second edge determiners, and first and second moving mechanisms are provided. The first and second coaters apply a coating solution for forming a heat-resistant protection layer onto both surfaces of a substrate on each of which an active material layer is previously formed. The first and second edge determiners determine the locations of lateral edges of the active material layers formed on both surfaces of the substrate to be coated by the respective first and second coaters. The first and second moving mechanisms move the location of the substrate along the width thereof based on the locations of the lateral edges determined by the first and second edge determiners, respectively. The locations of regions of both surfaces of the substrate to be coated are separately adjusted.

    摘要: An electrode body includes a positive electrode and a negative electrode. The positive electrode includes a positive electrode current collector and a positive electrode mixture layer disposed on the positive electrode current collector. The negative electrode includes a negative electrode current collector, a negative electrode mixture layer disposed on the negative electrode current collector and an insulation layer disposed on the negative electrode mixture layer and containing insulation particles. An insulation layer containing the insulation particles is formed on a side surface of width-direction end of the negative electrode so as to cover the side surface of the end portion.

    摘要: A secondary battery 100 comprises a positive electrode current collector 221 and a positive electrode active material layer 223 applied on the positive electrode current collector 221 and containing at least a positive electrode active material. The lithium-ion secondary battery 100 further comprises a negative electrode current collector 241 provided so as to oppose the positive electrode current collector 221 and a negative electrode active material layer 243 applied on the negative electrode current collector 241 and containing at least a negative electrode active material. The lithium-ion secondary battery 100 is also formed with a porous insulating layer 245 which contains stacked resin particles having insulating properties and is formed so as to cover at least one of the positive electrode active material layer 223 and the negative electrode active material layer 243 (in this case, negative electrode active material layer 243). The lithium-ion secondary battery 100 further comprises, on the edge of the insulating layer 245, a molten part 246 where the resin particles are melted.
