никель-металлогидридный аккумулятор

А comparanive stady was made of specific discharging capacity of metal hydride electrodes (МН) based jn a hydrogen-sorbing AB2 alloy  (ZrNi1.2Mn0.5Cr0.2V0.1) and its compositions with an AB5 alloy [ the intermetallide LaNi; with predominating components (Co, Mn, Ca)] in thecourse of the nickel-metal hydride battery formation. The formation of the active mass of the MH electrode (on the fifth charge-discharge cycle) has been found to proceed most effectively at a powder composition ratio of alloys AB2 : AB5 = 1:1

A comparative study of electrochemical characteristics of alloy compositions hydrogensorbing type AB₅ – Nickel (as an activator, a conductive additive), depending on the size distribution of the components have been done.

A comparative study was made of the electrochemical characteristics of metal hydride (MH) electrodes based on powder compositions of various granulometric characteristics. The electrochemical discharge capacity of the MH electrode has been found to be strongly dependent of the linear grain size of the hydrogen-sorbing alloy and carbonylic nickel. An increase in the dispersity degree of the hydrogen-sorbing alloy powder leads to reduction of the discharge characteristics of the MH electrode. A reverse dependence is observed for carbonylic nickel.
