LITHIUM SECONDARY BATTERY

In some embodiments, a lithium secondary battery is provied. The battery can include a laminate in which positive electrodes and negative electrodes are laminated in a lamination direction. A separator can be interposed between the positive electrode and the negative electrode. A first current collector can be present, the first current collector comprising a pair of conductive layers and a resin layer. The pair of conductive layers can sandwich the resin layer. The first current collector including a first end part. A first electrode tab electrically connected to the first end part can be present. A sealed container can be present including a sealing part. The sealed container can be configured to sandwich the first insulating part of the first electrode tab at the sealing part and to allow a part of the first electrode tab to be taken out to an outside of the sealed container.
