| titleOfInvention | Evaluation method of positive electrode active material for secondary battery |
| abstract | The present invention provides a technique capable of accurately evaluating load characteristics resulting from the performance of a positive electrode active material. A dQ / dV curve (vertical axis: dQ / dV, horizontal axis: differentiated with respect to a potential V which is a battery voltage) of a battery capacity Q with respect to a positive electrode mixture portion composed of a positive electrode active material for a secondary battery. V), when there are two or more peaks in the dQ / dV curve in the charging process, the potential difference (dQ / dV curve) between the peak with the lowest potential and the peak with the highest potential. Of the peak having the lowest potential and the potential difference between the peaks (width in the horizontal axis direction on the dQ / dV curve) is greater than or equal to the reference value b. Provided is a positive electrode active material evaluation method for a secondary battery, in which when the potential (horizontal axis value in the dQ / dV curve) is a reference value c or less, the load characteristics of the positive electrode active material are evaluated to be good.
