Electric field module distribution of the nanowalls (left) and core-shell (right) electrodes in 1 M KOH solution for 0.4 V applied bias, as simulated by COMSOL Multiphysics software. A 20 nm thick Ni(OH)2 nanosheet was used to simulate the nanowalls electrode. A 17 nm thick Ni nanosheet surrounded by a 3 nm thick Ni(OH)2 shell was used to simulate the core-shell electrode. The following room temperature conductivities were used: 10−13 S cm−1 for Ni(OH)2, 105 S cm−1 for Ni, and 0.2 S cm−1 for 1 M KOH28,36.
