Abstract:
A lithium ion secondary battery in which a safety vent as a safety device for a swelling phenomenon functions under a low pressure. A notch is formed in an inner surface of a large-area wall of the secondary battery, and an auxiliary notch is formed in an outer surface to correspond to the notch formed in the inner surface.
