Title:
SECONDARY BATTERY AND SECONDARY BATTERY PACK INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2015005506
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a secondary battery capable of preventing an increase in an interface resistance, deformation, and occurrence of a fine short circuit of an electrode body, and a secondary battery pack including the secondary battery.SOLUTION: A secondary battery and a secondary battery pack including the secondary battery of the present invention include a first member for reinforcing rigidity and a second member deformed at a high temperature to allow an electrode body to be adhered, on one side or both sides of the electrode body accommodated and sealed in a pouch. Accordingly, even when the pouch is swelled due to gas generation at a high temperature, performance degradation can be prevented by preventing an increase in an interface resistance of the electrode body accommodated in the pouch and a fine short circuit can be prevented by preventing deformation of the electrode body, so that safety can be improved.
