Discharge profiles for the Li–O₂ cells: (a) with KB/CP, KB/SS, and CPs as cathodes; (b) with KB/CP as the cathode measured at the current density ranging from 50 μA·cm⁻² to 300 μA·cm⁻²; (c) with KB/CP and KB/SS as cathodes; (d) with SP/CP and SP/SS as cathodes. The PVDF ((a) and (b)), PVDF or PTFE ((c) and (d)) are used as the binders, respectively. The current densities in panels (a), (c), and (d) are all 100 μA·cm⁻².
