Computer aided design of NiMH electrodes

Abstract

Although a series of applicable and promising compositions of NiMH electrode have been proposed in the literature, it is time and cost intensive by using 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 analyzed by applying various artificial intelligence techniques on literature experimental 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 capacity and cycle life of rare earth nickel metal hydride electrodes. In particular, a new design of electrode chemistry and its chemical stability are discussed.
