| titleOfInvention |
Film-covered battery and assembled battery |
| abstract |
The invention provides a closed type battery comprising a battery element covered with a covering film and a heat fusion seal portion formed by heat fusion on a periphery of the covering film, wherein the cleaving strength upon an internal pressure rise of a seal portion positioned between a positive electrode terminal and a negative electrode terminal is larger than that of any other seal portion, and a safety valve adapted to release pressure upon a battery's internal pressure rise is located at a portion other than said inter-terminal seal portion. The invention also provides an assembled battery wherein a plurality of closed type batteries are stacked one upon another while a safety valve adapted to release pressure upon an increase in the internal pressure of the battery is located at a position in no contact with the covering film surface of an adjoining battery. |
