摘要：
An improvement of discharge capacity of metal-hydride electrodes based on hydrides of Ti4-xZrxNi2Oy alloys (0.2 less than or equal tox less than or equal to0.6; 0.2 less than or equal to y less than or equal to 1.0) was shown during simultaneous partial Ti --> Zr substitution and oxygen modification. The maximal value of C-p (311 A h (.) kg(-1)) was experimentally found for a metal-hydride electrode based on Ti3.6Zr0.4Ni2O0.6H5.2. High cyclic stability was shown for the oxygen-containing Ti3.6Zr0.2V0.2Ni2O0.3 and Ti3.8V0.2Ni2O0.3 alloys alloyed with vanadium.
