ELECTRODE MATERIAL EVALUATION METHOD, ELECTRODE MANUFACTURING METHOD, AND ELECTRODE MANUFACTURING DEVICE |
摘要 |
<P>PROBLEM TO BE SOLVED: To suppress decreasing of a production yield of an electrode by measuring impurities contained in an electrode material. <P>SOLUTION: An evaluation method of the electrode material for a nonaqueous electrolyte secondary battery includes: a step (A) which successively oscillates the electrode material for the nonaqueous electrolyte secondary battery with a predetermined frequency in a magnetic field of two or more levels of different flux densities; a step (B) which detects induced magnetization synchronized with the oscillation generated in the electrode material; and a step (C) which obtains saturated magnetization of the electrode material from the induced magnetization. <P>COPYRIGHT: (C)2009,JPO&INPIT |
