a XRD patterns of stripped/plated zinc electrodes in Zn||Zn cells, b associated SEM images of the plated side. Zn | |Zn cells cycled at c 1 mA cm−2, 1 mAh cm−2 and d 10 mA cm−2, 1 mAh cm−2. e Zn||Cu cells cycled at 1 mA cm−2, 1 mAh cm−2. f Comparison of achieved cycling performance with values reported in the literature (estimated by simplified ex-post calculations). It is noted that the cycling measurements were conducted at around 25 oC and “-S” and “-P” in (a) denote a complete stripping and plating process, respectively.
