| Abstract: |
| Using the compression set of a certain power battery fluororubber sealing ring（referred to as fluororubber sealing ring） as the aging index，accelerated aging tests were conducted on the fluororubber sealing ring at three temperatures（85，100 and 120 ℃） and two initial compression rates（25% and 40%） to evaluate the reliability of storage life of the fluororubber sealing ring.According to the accelerated aging kinetic equation，the static sealing storage life of the fluororubber sealing ring at a temperature of 80 ℃ and an initial compression rate of 25% was 38.22 a. |
