Fig. 5: Electrochemical performance of MCMB||LNMO and MCMB||LNMO-C0.5La full cells at 26 °C.

a Initial charge/discharge profiles of the full cells at 72.5 mA g⁻¹. b The charge/discharge profiles of the full cells at 290 mA g⁻¹ (following constant current charge at 290 mA g⁻¹, an additional constant 4.8 V charge is applied until the current drops to 29 mA g⁻¹). c Long cycling performance of the full cells at a specific current of 290 mA g⁻¹ after initial five cycles at 72.5 mA g⁻¹. SC and CE represent specific capacity and Coulombic efficiency, respectively. d Nyquist plots of the full cells using LNMO and LNMO-C0.5La after an initial cycle at 72.5 mA g⁻¹. e Nyquist plots of the full cells using LNMO and LNMO-C0.5La after 1000 cycles at 290 mA g⁻¹. All the EIS spectra have been fitted using the equivalent circuit model shown in Supplementary Fig. 17, similar to literature⁴³. The key fitting results and errors are listed in Supplementary Table 2.
