an increasing trendno p-value reported

When the Ni doping amount was greater than 0.1, the polarization impedance showed an increasing trend again because with the continuous increase in the doping amount, the excessively high oxygen vacancy concentration caused defects in the cathode material and led to the localization of oxygen vacancies [ 21 ], thereby reducing the O ion transport rate and increasing R p .
