Title: Collector for secondary battery
Inventor: ASHIZAWA KOICHI
IPC: H01M4/02
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To provide a collector for a secondary battery difficult to cut even if excessive charging is applied to the secondary battery. SOLUTION: This collector for a secondary battery is formed out of metal foil. Disengagement energy of the metal foil is 1.0×104-1.0×107 J/m3. The release energy of the metal foil is obtained by converting a work volume required in a time span from a starting point of breaking to a cutting point when the metal foil is subjected to a tensile test to a value per unit volume. In order to obtain such metal foil having this disengagement energy, when the average thickness of the metal foil in its width direction is set for (t0), it is preferably formed so as to have a thickness of 1.03 (t0) at an at least one location in the width direction. In the collector of such metal foil, partial breaking is caused by excessive charging, however, in many cases, it does not get to the cutting point. Accordingly, when it is discharged after excessively charged, it is not easily disconnected and stable discharge becomes possible.

Subsequently, the purge value 25 is closed, so that the purge passage 21 is cut off from the atmospheric air so as to be held in a sealed condition for the predetermined time. After a lapse of the predetermined time, if a pressure increase inside the tank internal pressure is within the determination threshold valve, it is determined leakage is not caused.  After this leakage determination, failure determination for closed fixing in the atmospheric valve 28 or opened fixing in the control valve 24 is carried out according to a degree of pressure increase when the atmospheric air release valve 28 is opened and the control valve 24 is closed. Failure determination for opened fixing in the atmospheric air release valve 28 or closed fixing in the control valve 24 is carried according to a degree of pressure reduction when the pressure is reduced toward the predetermined negative pressure.
