    Abstract: A manufacturing method is provided for manufacturing an electrode for a lithium-ion battery having a current collector and an electrode active material layer. In the method, an electrolytic solution is added to particles created by pulverizing a mixture containing electrode active material particles and a pressure sensitive adhesive resin to obtain an electrode active material composition. The electrode active material composition is molded into sheet form on a current collector using a roll press. The electrode active material composition has a weight of the electrolytic solution based on a total weight of the electrode active material composition that is 0.1-50 wt %.

    Abstract: The battery pack has a laminated body in which unit cells are laminated one on another, a cell case having a first opening and containing the laminated body, and a first lid member to tightly close the first opening. The first opening is positioned to face, in connection with a unit cell laminated direction, a first face of the laminated body. The first lid member is configured to, if an internal pressure of the cell case is lower than atmospheric pressure, deform while keeping the tightly closing state, come into contact with the first face of the laminated body, and apply a pressure based on a differential pressure between atmospheric pressure and the internal pressure of the cell case to the contacting face.

    Abstract: An electrode for a secondary cell includes a current collector and an electrode layer. The electrode layer has a gas flow passage disposed on the surface and/or in the interior of the electrode layer. The gas flow passage extends in the in-plane direction of the electrode layer. The electrode layer is made from an electrode layer forming material that contains an electrode active material and an ion conductive liquid and is a non-bonded body. A secondary cell comprises a power generation element having an electrolyte layer, a positive electrode disposed on a first surface side of the electrolyte layer, and a negative electrode disposed on a second surface side on the back of the first surface side of the electrolyte layer; and an outer casing that houses the power generation element. At least one of the positive electrode and the negative electrode is the electrode for a secondary cell.
