ELECTRODE ACTIVE MATERIAL EVALUATION METHOD, ELECTRODE MANUFACTURING METHOD, ELECTRODE ACTIVE MATERIAL EVALUATION DEVICE, ELECTRODE ACTIVE MATERIAL EVALUATION SYSTEM, AND ELECTRODE MANUFACTURING SYSTEM

摘要

To provide an electrode active material evaluation method enabling an electrode active material occluded with lithium to be correctly evaluated, an electrode manufacturing method, an electrode active material evaluation device, an electrode active material evaluation system, and an electrode manufacturing system.SOLUTION: The electrode active material evaluation method is a method for evaluating an electrode active material occluded with lithium. In the electrode active material evaluation method, an aggregate including the electrode active material is pressurized to measure volume resistance, and the electrode active material is evaluated on the basis of a measured value of the volume resistance. It is preferable that pressure for pressurizing the aggregate is 0.001 MPa or more and 60 MPa or less. It is preferable to measure the volume resistance when 1 second or more has elapsed from a time when the pressurization of the aggregate is started and within 168 hours from the above time.SELECTED DRAWING: Figure 1
