Computer aided design of NiMH electrodes

Although a series of applicable and promising compositions of NiMH electrod e have been proposed in the literature, it is time and cost intensive by us ing experimental methods only. In this paper, the effects of La, Ce, Pr and Nd on charge discharge capacity and cycle life of NiMH electrodes are anal yzed by applying various artificial intelligence techniques on literature e xperimental data. This study shows that an increase in the ratios of La/Ce, Ce/Nd and a decrease in Pr are beneficial for both charge discharge capaci ty and cycle life of rare earth nickel metal hydride electrodes. In particu lar, a new design of electrode chemistry and its chemical stability are dis cussed.
