Abstract: | LaCrO3 was prepared by glycine combustion method and investigated as negative electrode for Ni/MH batteries. The structures of the as-calcined powder and the 20th charge-discharge cycle sample were characterized by XRD. The electrochemical experimental results demonstrated that the LaCrO3 electrode showed excellent electrochemical reversibility and considerably high charge-discharge capacity at various temperatures. Except for the charge-discharge cycle at 298 K, the discharge capacities of LaCrO3 electrode keep steady at 107.1 mA h g−1and 285 mA h g−1 at 313 K and 333 K after 5 cycles, respectively. |
