Abstract(in English) | The capacity of nickel-hydride battery using LaNi_5 system alloy is approaching its limits, because the repeated improvements to increase the discharge capacity have realized very high utilization of the intrinsic capacity. The hydrogen storage properties of the new ternary La-Mg-Ni system alloys, La_2MgNi_9, La_5Mg_2Ni_<23> La_3MgNi_<14>, were investigated. As a result, the negative electrode of the La_5Mg_2Ni_<23> alloy showed a large discharge capacity (410 mAh/g), 1.3 times larger than that of LaNi_5 system alloys. These La-Mg-Ni system alloys were found to be mainly composed by stacked AB_5 and AB_2 structure subunits in a superstructure arrangement. This alloy electrode was an effective way to improve the charge-discharge capability of the negative electrode. |
