Will the release of the safety valve be affected by battery aging?

Battery aging may bring a series of potential challenges and impacts to the release performance of the safety valve. As a battery continues to undergo charge and discharge cycles in use, its internal structure and chemical composition may gradually change, leading to a series of safety valve-related problems.

During battery aging, electrochemical reactions may trigger the formation of gases, especially hydrogen and oxygen. These gases accumulate inside the battery, increasing the internal gas pressure. The job of a safety valve is to monitor and control this internal gas pressure to prevent it from rising to dangerous levels. However, over time, the rate and amount of gas production may increase, causing the safety valve to trigger more frequently to release excess gas.

The sealing materials and mechanical components in safety valves are also inevitably affected by aging. This can lead to a decrease in sealing performance, making the safety valve more likely to trigger when pressure rises. Since the release mechanism of a safety valve is directly related to the reliability of these components, aging may exacerbate the risk of safety valve failure.

To cope with these challenges, regular maintenance and inspections become critical. This may include regularly replacing aging components in the safety valve, adjusting the relief pressure to suit changing conditions, or even replacing the entire safety valve if necessary. Such maintenance measures help ensure that the safety valve can still effectively perform its protective function despite the aging of the battery system and ensure the safety of the entire battery system.
