<p>PROBLEM TO BE SOLVED: To provide a quantitative method of the amount of gas generated in a secondary battery capable of easily and quickly quantitating the amount of generated gas, and accurately quantitating it even when the amount of generated gas is small.SOLUTION: In a quantitative method of the amount of gas generated in a secondary battery, an added gas is supplied into a laminate cell 1 in which the gas is generated therein, the same amount of sample gas as the added gas supplied into the laminate cell 1, is removed from the laminate cell 1 to measure a concentration of the added gas in the sample gas. The amount of gas generated in the laminate cell can be quantitated by measuring the concentration of the added gas in the sample gas. Since the added gas is simply supplied into the laminate cell 1 and the sample gas is simply removed to measure the concentration of the sample gas, the generated gas can be easily and quickly quantitated.</p> |
