<P>PROBLEM TO BE SOLVED: To provide a power storage device using positive and negative electrode terminals which generate no interspace even when the terminals have a large cross section. <P>SOLUTION: A power storage device comprises: positive electrodes 81, 41 made of a positive electrode current collector 82 coated with a positive electrode material; and negative electrodes 84, 44 made of a negative electrode current collector 85 coated with a negative electrode material. The positive and negative electrodes are laminated with a plate-shaped separator 87 interposed, and housed in containers 2, 20 in a state where they are immersed in an electrolyte 9. In this power storage device, positive electrode terminals 11, 42 electrically connected to tabs 88, 48 of the positive electrodes, and negative electrode terminals 12, 43 electrically connected to tabs 89, 49 of the negative electrodes are each pulled out to the outside of the containers. A positive electrode hole 22 through which the positive electrode terminal is inserted, and a negative electrode hole 23 through which the negative electrode terminal is inserted are formed at the container. The positive electrode terminal is pulled out to the outside of the container from the positive electrode hole, and the negative electrode terminal is pulled out to the outside of the container from the negative electrode hole, and the positive electrode hole and negative electrode hole are encapsulated under pressure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
