| 摘要 |
The present invention provides a means for minimizing and improving the reliability and safety of the electrochemical cells such as batteries, capacitors, or the like. The present invention involves forming one or more holes in an electrochemical cell such that the holes are connected to the outside, and attaching a gas permeable membrane around the hole such that the bonded surface of the gas permeable membrane is surface-treated in order to improve bonding properties. Thus, gas generated by the electrochemical cell is discharged to the outside to prevent the internal pressure of the electrochemical cell from rising, thereby reducing the weight and volume of the electrochemical cell and improving the reliability and safety thereof. |
