发明名称 METHOD OF MEASURING LITHIUM ION CONCENTRATION AND METHOD AND APPARATUS FOR MANUFACTURING LITHIUM SALTS BY UTILIZING THE SAME
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a method of easily measuring lithium ion concentration on-line when finding a solution which has a relatively high lithium ion concentration, has a relatively small amount of impurity content, and is suitable for manufacturing lithium salts and when manufacturing the lithium salts from the solution, and to provide a method of manufacturing lithium salts utilizing the method. <P>SOLUTION: A drain for manufacturing an active material is adopted, where lithium has been dissolved as solution having a relatively high lithium ion concentration and a relatively small amount of impurity content. Electric conductivity of the drain for manufacturing an active material is measured based on signals from an electroconductance meter 11, and a lithium ion concentration in the drain for manufacturing an active material is calculated from the electrical conductivity. More specifically, a lithium ion concentration is measured by utilizing electrical conductivity. A condensation process and a deposition process are controlled based on the lithium ion concentration calculated from the electrical conductivity, thus manufacturing lithium salts. <P>COPYRIGHT: (C)2011,JPO&INPIT</p>
