a The cross-section SEM image of the MLCC sample. b P-E loops as a function of electric field for the MLCC sample. c The evolution of Pm, Pr, and ΔP of the MLCC sample as a function of electric field. The fitting curve derived from the bulk ceramic data shows a good consistent with that of MLCC. d Comparison of the evolution of Wrec and η as a function of electric field for our MLCC sample with those of start-of-the-art Pb-free RFE MLCCs12,20,22. e Comparison of the temperature-dependent energy storage performances of our MLCC sample under 60 kV mm−1 with those of start-of-the-art Pb-free RFE MLCCs15,23,24. f Discharge reliability of the MLCC sample under an electric field of 60 kV mm−1.
