Al and Co co-doped α-Ni(OH)2 sample was prepared by a solid state reaction at a relatively low temperature.Its structure and electrochemical behaviors were investigated.The results of X-ray diffraction(XRD) show that Al and Co co-doped α-Ni(OH)2 maintains the structure of α-Ni(OH)2 in 6 mol/L KOH solution for 6 months and keeps the structure of α-Ni(OH)2 after 30 cycles of charge/discharge.The results of the electrochemical experiments show that Al and Co co-doped α-Ni(OH)2 exhibits a larger discharge capacity and a higher discharge potential and a high current density property than Al doped α-Ni(OH)2 and spherical β-Ni(OH)2.
