Abstract
Aluminium-substituted nickel based layered double hydroxides (LDHs), Ni0.78Zn0.04Co0.04Co0.02Al0.16(OH)2(CO3)0.08· 1.0H2O, were synthesized by a chemical co-precipitating process. It was shown that the structure of the LDHs is similar with that of α-Ni(OH)2 investigated by X-ray diffraction and transmission electron microscopy. The electrode comprising the LDHs was charged/discharged according to a galvanostatic model, and displayed better discharge capacity than the common β-Ni(OH)2 electrode. In addition, the effects of losing structure water on structure and electrochemical performance were investigated.
