BIPOLAR STORAGE BATTERY

WIPO Patent Application WO/2023/181796

A1

In the present invention, takt time is reduced and the occurrence of short-circuiting between the positive electrode side and the negative electrode side in a cell member interior is prevented by forming and disposing a through-hole with consideration to the ease of injection while ensuring, when an electrolytic solution is injected into a space where the cell member is housed, that pressure from the injected electrolytic solution does not affect constituent elements in the space, such as causing the separator to deform. The present invention comprises: a cell member (110) that is provided with a positive electrode (111), a negative electrode (112), and a separator (113) interposed between the positive electrode (111) and negative electrode (112), and that is disposed as a stack of such cell members with space therebetween; a space-forming member (120) that includes a substrate (121) and a frame (122); a plurality of through-holes (180) that open into a space (C) where the cell member (110) is housed; and a lid (190) that covers the portion of the frame (122) surrounding one side surface of the cell member (110), wherein the lid (190) has one communicating hole (191) for communicating the plurality of through-holes (180).
