a Cyclic stability of Zn//Zn symmetric cells at 2 mA cm−2/2 mAh cm−2 (insets are SEM images of Zn anodes after 75 cycles). b Voltage evolution of Zn//Zn symmetric cells at step-increased current densities. The c plating/stripping CE (inset is magnified view of selected cycles between the 100th and 2500th cycle) and corresponding d voltage profiles of Zn//Cu asymmetric cells at 5 mA cm−2/1 mAh cm−2. e A comparison of Zn plating/stripping performance in recent demonstrations with our work.
