The role of PTC in batteries？
PTC (Positive Temperature Coefficient), which means positive temperature coefficient, generally refers to semiconductor materials or components with large positive temperature coefficient. PTC materials have the characteristics that the resistivity increases with the temperature. When a large current passes through the PTC device, the Joule heat generated by PTC will cause the temperature to increase, and then the resistance of the element will increase rapidly, thereby limiting the current flow.
