Aluminum and zinc co-doped nano-nickel hydrox-ide was synthesized by chemical co-precipitating method using nick-el sulfate, aluminum nitrate and zinc nitrate as raw materials. The crystal structure, thermal stability and electrochemical properties of typical samples were tested by XRD, TG-DSC and cyclic voltam-metry(CV). The results show that aluminum and zinc co-doped na-no-nickel hydroxide is α-Ni(OH)2 crystals and its decomposition temperature is about 350℃.The average proton diffusion coefficient (DH) of samples doped with 15mol% Zn2+is 9.70 × 10-11 cm2 · s-1, which is highest among all the samples.
