Title:
LAMINATE BATTERY
Document Type and Number:
Japanese Patent JP2013030385
Kind Code:
A
Abstract:
To provide a laminate battery 10 capable of preventing displacement of winding/laminate of a collector which is connected to electrode tabs 12 and 13 to thereby prevent short-circuiting across collectors, and by preventing drop-off of active material provided to the collector due to a stress generated when the collector is pulled out, capacity drop of the battery is prevented.
Electrode tabs 12 and 13 each having bent-portions 23 are covered by an insulation coating. The insulation coating covering the bent-portions 23 is softer than that of the insulation coating covering the portions other than the bent-portions 23.
