Abstract Prussian blue analogues (Ni 3 [Fe(CN) 6 ] 2 )) derived nanocube‐like Ni(OH) 2 was grown evenly on the surface of GO via solution‐precipitation and potassium hydroxide etching process at room temperature. Due to the even dispersion of Ni(OH) 2 nancubes, the obtained sample Ni(OH) 2 /GO exhibits a maximum specific capacitance of 1299 F g −1 at 0.5 A g −1 , excellent electrochemical stability (capacity retention of 63% from 0.5 A g −1 to 10 A g −1 ), and long‐cycle stability (capacity retention of 78% over 2000 cycles).
