Document Type and Number:
Japanese Patent JP6950406
Kind Code:
B2
Abstract:
To provide a power storage element which enables the increase in energy density.SOLUTION: A power storage element 10 comprises: an electrode body 400; and a positive electrode current collector 700 and a negative electrode current collector 800 which are connected to the electrode body 400. The positive electrode current collector 700 has: two positive electrode-side connection parts connected to two positive electrode-side ends of the electrode body 400; and a positive electrode-side binding part 740 binding the two positive electrode-side connection parts, and disposed along a connection part with two positive electrode-side ends of the two positive electrode-side connection parts. The negative electrode current collector 800 has: two negative electrode-side connection parts connected to two negative electrode-side ends of the electrode body 400; and a negative electrode-side binding part 840 binding the two negative electrode-side connection parts, and disposed along a connection part with two negative electrode-side ends of two negative electrode-side connection parts. A width of the positive electrode-side binding part 740 in a direction in which the two positive electrode-side connection parts are arrayed is different from a width of the negative electrode-side binding part 840 in a direction in which the two negative electrode-side connection parts are arrayed.SELECTED DRAWING: Figure 8
