| Popis: | Tetragonal SnO compound was studied as the active electrode material in `Lithium-ion'-type cell. Structural and 119 Sn Mossbauer properties of SnO are presented. The results concerning X-ray powder diffraction (XRD) and 119 Sn Mossbauer spectroscopy of lithiated crystallised tin oxide SnO between 0 and 2 lithium inserted per formula were reported. During the lithium insertion a reduction of SnO in β-Sn and in an inter-metallic tin in strong interaction with the structural SnO (SnO→β-Sn and SnO→Sn(0)) is observed. When the cell is recharged, the mechanism is in part reversible with the reformation of the SnO but there is also the formation of Sn(IV) (Sn(0)→Sn(II)→Sn(IV)). |
