Electrolyte
its ignition point is around 200¡É, and flash point is below normal temperature, which is very low. When the electrolyte is dissolved, and the thickness of the battery becomes expanded. (expansion, cause of solution leak)
Lithium substance
The metal Lithium reacts actively to water generating hydrogen and heat. (Explosive)
Used as compound of Co oxide to enhance security and ion decomposition


CELL
Safety Vent
a part designed o lower the inner pressure of the battery which has been raised by
the air released.

PTC(Positive Temperature Coefficient)
when the temperature exceeds certain level, the resistance becomes infinite and shields
the conduction.
Function returned when the temperature descends

Shut-down Separator
separator itself melts when it is over the certain temperature so that ions cannot penetrate
Material of the separator: PP, PF or both used
⇒ Melting point: PE 140•C,PP 180•C

Additives : Active Material, Electrode, Electrolyte
substance for the battery Induces the safety of the battery

PACK
Safety Circuit
protects the electric conduction in case of over-current, over-voltage and overheat
Attached between the Anode and Cathode when packed
