Dicadmium Stannate as a Novel Electrode Material for Battery Applications

We have studied the behavior of prepared by reactive sintering of mixture, as the active material of secondary batteries. The constructed cell using this material as a negative electrode together with a positive electrode showed an open‐circuit voltage of 1.48V, which proved to be stable over a long period of time. The coulombic efficiency was close to 100% over at least 3000 complete charge‐discharge cycles at a constant current. The chemical stability of the electrodes and the nature of the surfaces were also studied by AES/EPMA/SEM techniques.
