Fig. 6. Electrochemical performances of Co–N/CNs-800 and Pt/C in a homemade all-solid-state Al–air battery device. (A) Schematic of the all-solid-state Al–air battery. (B) Discharge polarization curves and corresponding power density plots. (C) Discharge curves for all-solid-state Al–air battery with electrocatalysts of Co–N/CNs-800 and Pt/C at a constant discharge current density of 12.5 mA cm−2; inset, white LED lit up by three prepared devices in series.
