蓄電装置用電極体及び蓄電装置並びに車両
Document Type and Number:
Japanese Patent JP5621759
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrode body for power storage device that can improve volume energy density by reducing the dead space of a power storage device having a plurality of winding type power generating elements, and simplifies a structure of a collection terminal connected to the power generating elements.SOLUTION: An electrode body 10 for power storage device as the electrode body for power storage device is a winding type electrode body for power storage device such that a belt-like positive electrode 11 having an active layer and a belt-like negative electrode 12 having an active layer are wound with a belt-like separator 13 interposed therebetween. The belt-like positive electrode 11 and belt-like negative electrode 12 are wound so as to have two winding parts 14, and a collection terminal 15 for positive electrode and a collection terminal 16 for negative electrode are provided to the winding parts 14 on mutually different sides.
