摘要： A pressurizing structure for a storage battery applies pressure in a thickness direction to a structure including a storage battery cell with an electrode portion packaged with a laminate exterior material or including a laminate in which a plurality of storage battery cells are laminated. The pressurizing structure includes a pair of end plates disposed at corresponding ends of the structure in the thickness direction, and a fastening member configured to fasten the pair of end plates to each other. An elastic body is disposed at at least one position sandwiched between the end plate and the structure. A rigid body is disposed at a position sandwiched between the elastic body and the structure, and any one of the end plate, the elastic body, and the rigid body further includes a deformation preventing portion configured to prevent deformation of the elastic body in a direction perpendicular to the thickness direction.

摘要： 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.

摘要： A short circuit detection device has a voltage sensor and a control unit. The voltage sensor detects a voltage of a secondary battery. The control unit determines whether a first voltage value of the voltage of the secondary battery discharging to a load is below a threshold value. Upon determining the first voltage value is below the threshold value, the control unit adjusts the load to reduce the current that flows from the secondary battery to the load. The control unit then determines whether a second voltage value of the voltage of the secondary battery after the adjustment of the load is less than the first voltage value. Upon determining the second voltage value is less than the first voltage value, control unit recognizes that an internal short circuit of the secondary battery has occurred.
