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.
