a Representative CV curves for full E-Al82Cu18 | |AlxMnO2 (pink line) and Al | |AlxMnO2 (green line) Al-ion cells in 2 M Al(OTF)3 aqueous electrolyte with CO2 = 0.13 mg L−1. Scan rate: 0.1 mV s−1. b Typical voltage profiles of E-Al82Cu18 | |AlxMnO2 (pink line) and Al | |AlxMnO2 (green line) cells at the specific current of 0.1 A g−1. c Comparison of rate performance and Coulombic efficiency for E-Al82Cu18 | |AlxMnO2 (pink spheres) and Al | |AlxMnO2 cells (green squares), which are performed at various specific currents from 0.1 to 5 A g−1. d EIS spectra of E-Al82Cu18 | |AlxMnO2 and Al | |AlxMnO2 full cells. The pink sphere and green square symbols are the raw data of E-Al82Cu18 | |AlxMnO2 and Al | |AlxMnO2 full cells while the light pink and dark green lines represent their fit data, respectively. e Capacity retentions and Coulombic efficiencies of E-Al82Cu18 | |AlxMnO2 (pink spheres) and Al | |AlxMnO2 cells (green squares) in a long-term charge/discharge cycling measurement at 0.5 A g−1.
