Disclosed herein is a non-aqueous solvent secondary battery, which has excellent long-term reliability and high thermal-resistance through the improved thermal resistance of the collectors. The non-aqueous solvent secondary battery comprises a cathode electrically coupled to a collector, an anode electrically coupled to a collector and an electrolyte layer interposed between the cathode and anode. The cathode, anode and electrolyte layer are stacked upon one another. The collector of the cathode side comprises an alloy-based metal foil with at least a portion of the collector of the cathode side having a Pitting Resistance Equivalent (PRE) of 45 or more.

An electrode (100) of the present invention contains a collector (104) and an electrode layer (102) which is disposed on the collector (104) and contains an active material. In the electrode (100), an average thickness (h) of the collector (104) and the electrode layer (102) ranges from 5 to 300 (m, and a maximum thickness (h) of the collector (104) and the electrode layer (102) is not more than 105% of a minimum thickness (h) of the collector (104) and the electrode layer (102). The electrode (100) is very thin and the uniformity of the electrode layer (102) is high. Therefore, the heat dissipation characteristics of the battery (300) are uniform, the local degradation is hardly generated in the battery (300), and the crack and the rupture are also hardly generated in the battery (300).

Embodiments of a battery taught herein are directed to preventing a displacement between bipolar battery stacks or between a bipolar battery stack and an electrode tab. A bonding portion is formed at a part of a contact surface where a collector positioned at both ends in a stacking direction of a bipolar battery stack is bonded to the electrode tabs. The electrode tab and the collector are fixed by such a bonding portion. Further, the bonding portion is formed at a part of a contact surface where adjacent bipolar battery stacks are bonded to each other. Bipolar batteries positioned at upper and lower portions in the stacking direction are fixed by such a bonding portion.

摘要:
A battery includes a battery enclosure (3), a power-generating unit (50) accommodated in the battery enclosure (3), positive and negative terminal electrodes (1, 2). The battery enclosure (3) is composed of a laminate film compounded of metal and a polymer material, and has a rectangular shape. The power-generating unit (50) includes positive electrode collectors (5), negative electrode collectors (7) and separators (8). The positive and negative terminal electrodes (1, 2) have dimensions substantially equal to those of the positive and negative electrode collectors (5, 7), respectively. Further, the positive and negative terminal electrodes (1, 2) protrude from mutually different sides of the battery enclosure (3). The positive terminal electrode (1) is formed by protruding the positive electrode collectors (5) from the battery enclosure (3) in a state where end portions of the positive electrode collectors (5) are mutually stacked. The negative terminal electrode (2) is formed by protruding the negative electrode collectors (7) from the battery enclosure (3) in a state where end portions of the negative electrode collectors (7) are mutually stacked.
