Description

<p>Possibility as an electrode by using vanadium hydride, which is one of typical metal hydrides as hydrogen storage alloy, was examined for an all solid lithium ion battery. The results obtained show vanadium hydride as a negative electrode material by conversion reaction were clarified for the first time in this work. By analyzing the charging/discharging properties and XRD profiles for each process, the reaction mechanism of the conversion reaction of vanadium system and lithiation reaction of hard carbon was clarified.</p>
