ELECTRODE EVALUATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electrode evaluation method capable of evaluating electrodes without being affected by external factors during the evaluation of the electrodes.SOLUTION: An electrode evaluation method for detecting a difference in structure of electrodes used for a secondary cell includes: a step (S12) of measuring resonance frequencies of a first sample prepared from the electrodes and measuring resonance frequencies of a second sample prepared from the electrodes; and a step (S13) of comparing the resonance frequencies of the first sample to the resonance frequencies of the second sample.SELECTED DRAWING: Figure 3
