a) Lithium striping and plating curves of the Li/Li symmetrical cells with middle layer SPE(blue) and anode contacting layer/middle layer/anode contacting layer SPE(red) at current density of 0.25 mA cm−2 (60 °C). b) Lithium striping and plating curves of the Li/Li symmetrical cells with anode contacting layer/middle layer/anode contacting layer SPE at current density of 0.25 mA cm−2 with areal capacity from 0.25 to 2 mAh cm−2 (60 °C). c) Rate performance of the Li/Li symmetrical cells measured under different current density with anode contacting layer/middle layer/anode contacting layer SPE; The cross‐sectional SEM images of Li metal disassembled from the Li/Li symmetrical cells d–f) with middle layer SPE and g–i) with anode contacting layer/middle layer/anode contacting layer SPE after 1, 5, and 10 cycles, respectively.
