Abstract:
1. A power storage module comprising: a plurality of cell units which are stacked; and a pressurizing mechanism which applies a compressive force in a stacked direction to a stacked structure of the cell units, wherein each of the cell units includes: a power storage cell, which includes a pair of electrode tabs; and a frame body which supports the power storage cell, wherein the frame body includes a positioning portion and a screwing portion, the positioning portion restraining a relative position with respect to a direction perpendicular to the stacked direction of the frame bodies adjacent in the stacked direction, the screwing portion being formed on a surface of an outer circumference side of the frame body, wherein the positioning portion includes a structure which positions the frame bodies with respect to the direction perpendicular to the stacked direction and leaves a margin in a direction in which the frame bodies are closer in the stacked direction in a state where the compressive force is applied to the stacked structure due to pressurization through the pressurizing mechanism, and wherein the electrode tab of the power storage cell and the electrode tab of the adjacent power storage cell are laminated with each other and fixed to the frame body at the screwing portion.
