Scan rate dependence of electrode activity and their performance under bending deformations. a Steady state polarization curves at varying scan rates of 2, 5, 10, 15, 20, 25, 50, 75, and 100mVs−1 for NiFe/Ni-P and NiMo/Ni-P under OER and HER conditions, respectively. b Flexibility studies of NiFe/Ni-P and NiMo/Ni-P electrodes showing the overpotentials required to reach current densities of 50 and −10mAcm−2, respectively at different bending angles with corresponding digital images. Insets show full steady state LSVs at different bending angles along with the definition of ‘bending angle’ (top)
