Title:
BIPOLAR STORAGE BATTERY
Document Type and Number:
WIPO Patent Application WO/2024/029366
Kind Code:
A1
Abstract:
According to the present invention, holding of an active material which is filled, while being prevented from the occurrence of a reaction that generates heat, is adequately maintained, thereby ensuring adhesion between the active material and a collector. A bipolar storage battery according to the present invention comprises: a cell member (110) that is provided with a positive electrode (111), a negative electrode (112) and a separator (113); and a space formation member (120). With respect to this bipolar storage battery, an active material layer (111b) for the positive electrode and an active material layer (112b) for the negative electrode each contain an active material; the active material layer (111b) for the positive electrode and/or the active material layer (112b) for the negative electrode have an active material holder (180) that holds the active material; and the active material holder (180) is arranged within the active material layer (111b) for the positive electrode or the active material layer (112b) for the negative electrode when viewed from the thickness direction of the active material layer (111b) for the positive electrode or the active material layer (112b) for the negative electrode, while being provided with a plurality of first bones (181) and a plurality of second bones (182), which intersect with the plurality of first bones (181), the first and second bones being formed of a material that is not chemically bonded to and is not reactive with the active material.
