POUCH-TYPE SECONDARY BATTERY HAVING IMPROVED HEAT-SAFETY |
摘要 |
The present invention relates to a pouch-type secondary battery having improved heat safety, a secondary battery, and a battery module. More particularly, overheat or ignition which can be generated when a conductive aciform material penetrates the secondary battery, and a melting phenomenon when additional heat is generated due to a short circuit between the batteries are prevented by forming a heat-resistant coating layer made of heat-resistant polymer in the outer surface of a secondary battery pouch. Thereby, the generation of electrolyte eruption can be prevented. Therefore, the safety of the secondary battery using the secondary battery pouch, the battery module, and a battery pack can be improved. |
