Perovskite-type LaCrO3 used as negative electrode for Ni/MH batteries was prepared by Pechini method and characterized by XRD and SEM. The electrochemical properties under various temperatures and electrolyte concentrations were investigated. The results showed that the discharge capacity of LaCrO3 electrodes increased with the increase of temperature and electrolyte concentration. Meanwhile, the electrochemical properties of LaCrO3 electrodes were found to be greatly influenced by the dimension of Ni powders, which served as catalyst in electrodes. EIS was employed to study the phenomena above.
