Abstract
A rechargeable battery having improved temperature detection performance of a resistor element. The rechargeable battery comprises a pouch in which an electrode assembly is embedded, a first terminal and a second terminal that are connected to the electrode assembly to be drawn out to one side of the pouch, a resistor element connected to the first terminal, and a pressing member that is coupled to the pouch and closely contacts one surface of the resistor element, having a positive temperature coefficient, to the pouch.
Claims10
A rechargeable battery having an electrode assembly, the rechargeable battery comprising:
- a pouch housing the electrode assembly, a pair of electrode tabs of the electrode assembly extending outside the pouch;
- a resistor element attached to one of the electrode tabs, the resistor element being in direct contact with the pouch, the resistor element having a positive temperature coefficient;
- and
- a pressing member engaged with the resistor element and coupled to an outside surface area of the pouch, the contact between the resistor element and the pouch being maintained by the pressing member, the pressing member comprising a cavity defined by:
- an upper portion;
- first and second side walls extending from the upper portion;
- and
- a front wall extending from the upper portion between the first and second side walls, the cavity comprising:
- a protruding portion extending from the upper portion between, but not in contact with, the first and second side walls and the protruding portion being in direct contact with the resistor element such that the contact between the resistor element and the pouch is maintained by the protruding portion.
