최근 들어 블리스터 포장방식은 제품을 뜯어보지 않고 제품을 확인할 수 있는 장점을 가지고 있어 여러 가지 상품포장에 이용되고 있다. 대부분의 건전지의 포장 역시 블리스터방식을 이용하여 포장을 하고 있다 그런데 카메라 및 각종 휴대용 전자장치에서 널리 사용되고 있는 리튬전지의 경우에서는 전지 자체가 가지고 있는 폭발위험성 때문에 블리스터 포장을 할 때 각별한 주의가 필요하다. 그러나 국내를 비롯한 국외에서도 일반 알카라인 전지 포장기계를 구조 변경하여 사용하고 있고 리튬전지 특성을 고려한 리튬전지 전용 블리스터 포장기는 개발되지 않고 있다.(중략)

The blister packaging is applied to many fields in recent years for its merit that it enable consumer to see the products. The most of battery packaging are blister type. However, the lithium battery is dealt with very carefully in packaging because of its explosion. The existing packaging machines for lithium battery are mostly adapted alkaline packaging machine and their capacity is very inferior to other process, either. In this paper, the virtual prototype of the automatic blister packaging system for lithium battery which has new mechanism and 240A/min capacity is developed and its performance is evaluated.

Temperature distribution of battery module consists of 11 batteries of 90Ah rate is analyzed using commercial software NISA II. Equivalent thermal resistance network is used to reduce the number of element in calculating heat transfer through a medium composed of several different thermal conductivity layers. Orthotropic model is used to put different thermal conductivity values according to Cartesian coordinate. Aluminum cooling fins are inserted in the middle of batteries to reduce battery module temperature. The cooling fin at the end of the module does not necessary in reducing maximum temperature. Combined effect of front and side cooling fin is analyzed to reduce the temperature difference among batteries. The maximum temperature difference among batteries is reduced within $3^{\circ}C$ when 4 aluminum cooling tin of 1mm thickness is inserted in battery module.
