Leak Detection of Lithium-Ion Batteries and Automotive …
Even though battery leak rate standards have yet to be established, HMSLD is the preferred choice as the leak rate required to ensure battery tightness is in the 10–6 to 10–10 atm-cc/s range or lower. To help determine the required leak rate for batteries or other automotive components, the following formula are used to
