Abstract

The two stable species of dicadmium stannate, namely oxidized (yellow) and reduced (green), have been studied using X-ray diffraction (XRD), Auger, and electron spectroscopy for chemical analysis (ESCA) techniques. Semiquantitative ESCA showed a chemical formula of Cd2SnO4 for yellow and Cd2SnO2 for the green compound. It appeared that both tin and cadmium can undergo a change in valency state during the electrochemical reduction. This explains the high energy density of the compound when used as active material for the negative electrode in rechargeable batteries. The variation of electrical conductivity of dicadmium stannate prepared under different conditions can be explained in terms of the reduction of tin, cadmium or both in the original compound.
