A study on the e%ect of annealing treatment on the electrochemical properties of La0.67Mg0.33Ni2.5Co0.5 alloy electrodes
International Journal of Hydrogen Energy 28 (2003) 113-117，-0001，（）：
In this paper, the influence of heat treatment on the electrochemical properties of La0.67Mg0.33Ni2.5Co0.5 alloy electrodes has been studied. The results show that, after heat treatment, the electrochemical properties including the discharge capacity, width of discharge plateau and cyclic stability have been improved markedly. The discharge capacity of the alloy annealed at 1123K is the highest and the cycle life of the alloy annealed at 1223K is the longest, respectively. In addition, the exchange current density I0 and the limiting current density IL of the alloy electrode both increase when annealed at 1123K and then decrease when the annealing temperature increases to 122 K.
