Abstract

본 발명은 스파이어릴 리튬전지의 상측 소정부위에 구비되는 방폭구조의 상부캡에 관한 것으로, 스파이어릴 리튬전지(1)가 과전류, 단락 또는 발열등으로 폭발되게 될 때 주변의 인명을 좀더 안전하게 보호할 수 있도록 하고자 하는 경우에 상기 스파이어릴 리튬전지(1)의 상부캡(14)에 소정의 방사형개구가 형성되어 있지 않음으로 인해 상기 스파이어릴 리튬전지(1)의 폭발시 상당한 고압력이 순간적으로 스파이어릴 리튬전지(1)의 상부캡(14)에 가해짐에 따라 커다란 인명사고를 발생시키게 되는 문제점을 해소하기 위하여, 전지캔(2)의 상측에 내측으로 알류미늄포일(12), 지지링(11) 및 PTC소자(13)가 적층되는 상기 PTC소자(13)와 상측에 구비되는 상부캡(14)의 벤트홀(9)을 대신하여 상측에 양측으로 각각 대향되게 절곡되는 방사형개구(16)가 형성됨으로써 스파이어릴 리튬전지(1)의 폭발시 발생되는 압력이 상기 상부캡(14)의 방사형개구(16)를 통해 적절히 분산될수 있게 되어 인명피해를 좀더 줄일 수 있게 되는 효과가 있다.The present invention relates to an upper cap of an explosion-proof structure provided at an upper portion of a spiryl lithium battery, and to protect the surrounding life more safely when the spiryl lithium battery 1 is exploded due to overcurrent, short circuit or heat generation. When a certain radial opening is not formed in the upper cap 14 of the spiryl lithium battery 1, a considerable high pressure may suddenly spy upon explosion of the spiryl lithium battery 1. In order to solve the problem of causing a great life accident as applied to the upper cap 14 of the lithium battery 1, the aluminum foil 12, the support ring 11 inward on the upper side of the battery can 2 And radial openings 16 that are bent in opposite directions on both sides in place of the vent holes 9 of the upper cap 14 provided on the upper side and the PTC element 13 on which the PTC element 13 is stacked. By being The pressure generated during the explosion of the pie childhood lithium battery 1 is able be properly distributed through the radial opening 16 of the upper cap 14 has the effect of being able to reduce the loss of life more.
