METHOD FOR MEASURING MOISTURE CONTENT OF ELECTRODE, METHOD FOR MANUFACTURING ELECTRODE FOR LITHIUM ION SECONDARY CELL, MOISTURE CONTENT MEASUREMENT DEVICE, AND MOISTURE CONTENT MEASUREMENT METHOD

摘要

This method for measuring the moisture content of an electrode includes at least the three steps (A) through (C) below. (A): A step for arranging an electrode (110) as a measurement sample in a container (105) provided with a gas introduction tube (101) and a gas outlet tube (103). (B): A step for supplying an inert gas heated to a predetermined temperature in advance to the container (105) from the gas introduction tube (101), and thereby heating the electrode (110) and vaporizing moisture adsorbed on the electrode (110). (C): A step for recovering the moisture vaporized from the electrode (110) together with the inert gas from the gas outlet tube (103) and quantifying the recovered moisture. This moisture content measurement device (100) is provided with: a container (105) for accommodating a measurement sample (100), the container (105) having a gas introduction tube (101) and a gas outlet tube (103); a heating means (107) for supplying an inert gas heated to a predetermined temperature in advance to the container (105) from the gas introduction tube (101) and thereby heating the measurement sample (110) and vaporizing moisture adsorbed on the measurement sample (110); and a moisture content measurement means (109) for recovering from the gas outlet tube (103) the moisture vaporized from the measurement sample (110) and quantifying the recovered moisture.
