BATTERY BLOCK, BATTERY MODULE, AND BATTERY BLOCK HOLDER

摘要

A battery block (1) comprises: a plurality of batteries (2) having a cylindrical outer shape; a case (3) for holding the batteries (2) along the outer circumferential side extending in the longitudinal direction of the batteries (2) such that the batteries (2) are aligned and arranged in a predetermined arrangement relationship by aligning the positive electrode sides of the batteries (2) on one side and the negative electrode sides thereof on the other side and the one side and the other side are opened; a positive electrode side collector (4) disposed at the opening on the one side of the case (3) and connecting the positive electrode sides of the batteries (2) to each other to collect electricity; a negative electrode side collector (5) disposed at the opening on the other side of the case (3) and connecting the negative electrode sides of the batteries (2) to each other to collect electricity; and two holders (6, 7) disposed attached to the respective facing sides of the outer shape of the case (3) and made of an insulator.
