Zusammenfassung:According to the present invention, disclosed is a battery pack having excellent durability. The battery pack having excellent durability according to the present invention includes: a plurality of battery cells made of a steel cylinder; and a bus bar electrically connecting electrode terminals of the battery cells. The battery pack has a flame-resistant layer disposed under the bus bar. Accordingly, the flame-resistant layer strengthens vibration resistance and at the same time improves heat dissipation, and is powdered to extinguish a fire when there is a problem in a unit battery and high heat is generated, thereby preventing the fire from spreading by adversely affecting adjacent batteries. 본 발명은 내구성이 우수한 배터리팩을 개시한다. 본 발명에 따르는 내구성이 우수한 배터리팩은 스틸재질의 원통형으로 이루어진 다수개의 배터리셀과, 상기 배터리셀들의 전극 단자들을 전기적으로 연결하는 버스바를 포함하는 배터리 팩에 있어서, 상기 버스바의 하부에 배치되는 내염층을 구비한 것을 특징으로 하는데, 이에 의할 때, 내진동성을 강화하는 동시에 방열성을 향상시키고, 단위 배터리에 문제가 있어 고열이 발생되는 경우에 분말화되어 화재를 소거하므로 인접한 배터리에 악영향을 미쳐서 화재가 확대되는 것을 방지할 수 있다.
