Abstract: 

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.
