  • Publication number: 20220059912
    Abstract: A power storage module comprises: an electrode stacked body including a stacked body in which a plurality of bipolar electrodes are stacked, a pair of terminal electrodes located on an outer side of the stacked body in a stacking direction of the bipolar electrodes, and a plurality of metal plates which constitute the stacked body and the pair of terminal electrodes; and a sealing body provided to surround a side surface of the electrode stacked body. The sealing body includes a plurality of first sealing portions coupled to edge portions of the plurality of metal plates, and a second sealing portion that couples the first sealing portions to each other. A thickness adjustment member that adjusts the thickness of the electrode stacked body in the stacking direction is disposed in the electrode stacked body at a position of overlapping the first sealing portions when viewed from the stacking direction.

  • Patent number: 11211668
    Abstract: A power storage apparatus has a case accommodating an electrode assembly, and a release valve present in the wall of the case. The electrode assembly includes electrodes. A shielding member is arranged between the inner surface of the wall and the end surface of the electrode assembly. A point located in a center of the case in a front view of the case taken in the stacking direction of the electrodes and located in a center of a dimension of the electrode assembly in the stacking direction is a center point, and a region surrounded by a plane connecting the center point and a contour of the pressure release valve at a shortest distance is a three-dimensional region. The shielding member includes a shielding portion that entirely covers a cross section of the three-dimensional region along the end face of the electrode assembly.

  • Patent number: 10943745
    Abstract: The electric storage device includes an electrode assembly having a positive electrode and a negative electrode, a case for housing the electrode assembly, a pressure relief valve, and positive and negative electrode conductive members that are electrically connected to the respective corresponding electrodes. The case has a wall in which the pressure relief valve is disposed. At least one of the positive and negative electrode conductive members includes an interposing portion located between the inner surface of the wall and an end face of the electrode assembly facing the inner surface, and a shielding portion located closer to the end face of the electrode assembly than the interposing portion. The shielding portion covers the pressure release valve from a side of the wall where the electrode assembly is located.

  • Publication number: 20200303702
    Abstract: This power storage apparatus has a case accommodating an electrode assembly and an electrolytic solution, and a release valve present in the wall of the case. The electrode assembly includes electrodes which have different polarities and are insulated from each other. A shielding member is arranged between the inner surface of the wall and the end surface of the electrode assembly. A point located in a center of the case in a front view of the case taken in the stacking direction of the electrodes and located in a center of a dimension of the electrode assembly in the stacking direction is referred to as a center point, and a region surrounded by a plane connecting the center point and a contour of the pressure release valve at a shortest distance is referred to as a three-dimensional region. The shielding member includes a shielding portion that entirely covers a cross section of the three-dimensional region along the end face of the electrode assembly.
