METHOD FOR DETERMINING CONTAINER LEAKAGE |
摘要 |
A method and apparatus suitable for use in high volume production for determining leakage from a nominally sealed product container, e.g., a battery case. The method and apparatus first functions to analytically test for leakage of a particular component of interest, e.g., a liquid electrolyte comprising a mixture of ethylene carbonate (EC) and methyl-ethyl carbonate (MEC) in a lithium-ion battery. A second gas leakage test can then be performed. |
