Abstract
Official abstract text for this publication.
A secondary battery manufacturing method according to an example embodiment of the present disclosure includes an electromagnetic welding step of joining together a first metallic component and a second metallic component included in the secondary battery by electromagnetic welding, and a laser welding step of applying laser light to weld an unjoined part of the first metallic component and the second metallic component, the unjoined part being not joined by the electromagnetic welding step.
First claim
Opening claim text (preview).
1 . A secondary battery manufacturing method comprising: an electromagnetic welding step of joining together a first metallic component and a second metallic component included in the secondary battery by electromagnetic welding; and a laser welding step of applying laser light to weld an unjoined part of the first metallic component and the second metallic component, the unjoined part being not joined by the electromagnetic welding step. 2 . The secondary battery manufacturing method according to claim 1 , wherein the electromagnetic welding step electromagnetically welds a plurality of first metallic components and a plurality of second metallic components simultaneously. 3 . The secondary battery manufacturing method according to claim 1 , wherein the first metallic component and the second metallic component are made of the same type of metal. 4 . The secondary battery manufacturing method according to claim 3 , wherein the first metallic component and the second metallic component are made of aluminum. 5 . The secondary battery manufacturing method according to claim 1 , wherein the first metallic component and the second metallic component are made of different types of metal. 6 . The secondary battery manufacturing method according to claim 5 , wherein the first metallic component is made of aluminum, and the second metallic component is made of copper. 7 . A secondary battery comprising: a first metallic component; and a second metallic component, wherein a joint surface of the first metallic component and the second metallic component includes an electromagnetically welded part and a laser-welded part. 8 . The secondary battery according to claim 7 , wherein the first metallic component and the second metallic component are made of the same type of metal. 9 . The secondary battery according to claim 8 , wherein the first metallic component and the second metallic component are made of aluminum. 10 . The secondary battery according to claim 7 , wherein the first metallic component and the second metallic component are made of different types of metal. 11 . The secondary battery according to claim 10 , wherein the first metallic component is made of aluminum, and the second metallic component is made of copper.
