Cylindrical battery
First Claim
1. A cylindrical battery comprising:
- an electrode body in which a negative electrode plate and a positive electrode plate to which a plurality of positive electrode leads is connected are wound with a separator interposed therebetween;
an upper insulating plate disposed on the electrode body;
a sealing body;
a current collector plate disposed between the upper insulating plate and the sealing body; and
an outer can,wherein the upper insulating plate has at least one through-hole,the plurality of positive electrode leads includes at least one first positive electrode lead disposed at an inner circumference side of the upper insulating plate and at least one second positive electrode lead disposed at an outer circumference side of the upper insulating plate,the first positive electrode lead extends between the upper insulating plate and the current collector plate after passing through the through-hole of the upper insulating plate and is bent onto the current collector plate at an outer circumference portion thereof,the second positive electrode lead extends along the outside of the outer circumference portion of the upper insulating plate and is bent onto the current collector plate at the outer circumference portion thereof,the first positive electrode lead and the second positive electrode lead are connected to the current collector plate, andthe current collector plate is electrically connected to the sealing body.

Abstract
A cylindrical battery including an electrode body in which a negative electrode plate and a positive electrode plate to which a plurality of positive electrode leads is connected are wound with a separator interposed therebetween; an upper insulating plate disposed on the electrode body; a positive electrode current collector plate disposed on the upper insulating plate; a sealing body; and an outer can. A first positive electrode lead extends between the upper insulating plate and the current collector plate after passing through a through-hole of the upper insulating plate and is bent onto the current collector plate at an outer circumference portion thereof, and a second positive electrode lead extends along the outside of an outer circumference portion of the upper insulating plate and is bent onto the current collector plate at the outer circumference portion thereof. Those positive electrode leads are all connected to the current collector plate.
