RECTANGULAR ELECTRICITY STORAGE DEVICE

WIPO Patent Application WO/2020/090409

A1

The present invention provides a rectangular electricity storage device which is reduced in weight, while ensuring the stiffness of an insulating sheet, and which ensures a space where an electrode body swells during the charging. A rectangular electricity storage device according to one embodiment of the present disclosure is provided with: an electrode body (11) which comprises a positive electrode plate, a negative electrode plate and a separator that is arranged between the positive electrode plate and the negative electrode plate; an insulating holder (30) which is obtained by shaping an insulating sheet (31) into a box shape, and in which the electrode body (11) is contained; a rectangular outer case which has an opening, and in which the electrode body (11) and the insulating holder (30) are contained; and a cover body which covers the opening of the outer case. The insulating sheet (31) comprises a porous body.
