Study on Preparation and Properties of β-NiOOH
Year: 2011
Type: article
Abstract: Taking β-Ni(OH)2 powder as raw material and K2S2O8 as oxidant, β-NiOOH was prepared through chemical oxidation process, then which was used as cathode material to assemble nickel-zinc cell. Effects of reaction time, reaction temperature, NaOH concentration, Ni(OH)2 concentration and mass ratio of K2S2O8 and Ni(OH) 2 on 1st discharge specific capacity of cells were studied. XRD result indicates that the crystal structure of β-NiOOH is disordered in a way. TG-DTA analysis indicates that the decomposition reaction of β-NiOOH occurs at temperature of 156-280 °C, the end product is NiO.
