池などがある。Many of the unit cells used in these battery packs are of a sealed type for the purpose of preventing leakage of the electrolytic solution and blocking the contact between the power generating element of the unit cell and the air. And, in such a sealed battery, in order to prevent the explosion of the unit cell due to an abnormal increase in the internal pressure of the unit cell when the battery is misused or at the end of the battery life, etc. When the internal pressure of the unit cell rises above a specified value, a safety valve that releases the internal gas to the outside of the unit cell is provided. Such sealed unit cells include manganese dry batteries, alkaline manganese dry batteries, lithium primary batteries, nickel-cadmium storage batteries, nickel-metal hydride storage batteries, nickel-zinc storage batteries, lead storage batteries and lithium secondary batteries.

ガスが電池パックの容器内に蓄積してその内部圧力の上
昇を招き、極端な場合には、電池パック自体のフクレや
破裂を招くおそれがある。The simplest way to meet this requirement is to completely seal the battery pack container. However, in this case, when the safety valve of the sealed unit cell is activated and its internal gas is released to the outside of the unit cell, the gas accumulates in the container of the battery pack and causes an increase in its internal pressure, In extreme cases, the battery pack itself may blister or explode.

ることが防止される。That is, the water-repellent porous film having air permeability allows gas to pass therethrough, but repels liquid such as water having a large contact angle. Therefore, if the container of the battery pack is provided with a communication hole between the inside and the outside thereof and the communication hole is partitioned by the water-repellent porous film having air permeability, the container is released from the safety valve of the sealed unit cell. The internal gas of the unit cell that passes through the communication hole and the porous membrane of the battery pack container is released to the outside of the battery pack, so the internal gas of the unit cell released from the sealed battery enters the inside of the battery pack. Accumulation is prevented.
