Document Type and Number:
Japanese Patent JP5891980
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power storage device in which heat dissipation is enhanced, and abrasion resistance and durability are enhanced even if it is used in a state of vibration.SOLUTION: In a secondary battery 10 as a power storage device, an electrode assembly 12 is housed in a case 11 constituted of a case body 11a having an opening 11c through which the electrode assembly 12 can be inserted, and a lid 11b closing the opening 11c, and the cover 11b is welded to the case body 11a so as to cover the opening 11c. The case body 11a and the cover 11b are made of aluminum or an aluminum alloy. A nitride layer 25 having high heat dissipation and abrasion resistance is formed at least on the side face 11d of the case body 11a, while leaving a welding margin 24 to the lid 11b at the rim of the opening 11c in the case body 11a.
