Abstract
A small protector is provided for a high energy density battery such as a lithium ion battery. A flat sheet form of leading portion extending from a positive temperature coefficient element is provided thereon with at least one battery protecting circuit element for detecting at least one abnormality selected from overcharging, over-discharging, overcurrent, and unusual temperature to cut off a current passing therethrough. A fail-safe mechanism is achieved for the actuation of the positive temperature coefficient element and the actuation of the battery protecting circuit element.
