“…During the first cathodic (lithium insertion) scan, an broad reduction peak around 0.96 V is observed and it almost disappeared during the sequent cycles. This irreversible peak could be ascribed to the process of the formation of the solid electrolyte interface (SEI) layer on the surface of the active material, the reduction of SnO 2 to the metal Sn and the simultaneous formation of Li 2 O amorphous matrix [21]. The cathodic peak around 0.34 V corresponds to the formation of Li x Sn alloys.…”

The ZnO/SnO 2 composite thin films were prepared on copper collectors as anode for LIBs by electron beam evaporation, with ZnO thin layer grown by magnetron sputtering. The structure, surface morphology and elemental composition were investigated by X-ray diffraction and scanning electron microscopy with an energy-dispersive X-ray spectrometer. The active materials were mainly composed of tin oxide thin films characterized with nanosized particles with dozens of nanometers. The cyclic voltammograms (CV), discharge/charge and rate performances were employed to characterize electrochemical properties of prepared thin-film electrode material. The CV curves revealed a typical alloying/dealloying of tin oxide with stepwise redox reactions according to the cathodic and anodic peaks. The significant improvement in specific capacity is observed in the curves of ZnO/SnO 2 thin-film electrode, comparing with alone SnO 2 thin-film anode. The discharge-specific capacity for ZnO/SnO 2 thin film is 758. 93, 465.7, 430.9, 344.7, 246.3 and 152.4 mAh/g, at the rate of 0.05C, 0.2C, 0.5C, C, 2C and 4C, respectively, about 5-10 times larger than that of alone SnO 2 thin-film anode. The rate performance of the composite thin film has also been enhanced by introducing the ZnO thin layer. It is a good strategy to applying the ZnO interlayer to strengthen the electrochemical performances of SnO 2 and decrease the irreversible capacity loss.

Zr-substituted SnO 2 -based ceramics (Sn 0.95-x Sb 0.05 Zr x O 2 , x B 0.1) were prepared by using a wet-chemical synthesis method. The results show that the prepared ceramics have a pure tetragonal phase as that of SnO 2 and have a typical characteristic of negative temperature coefficient (NTC) of resistivity over a wide temperature range from -50 to 300°C. The room-temperature resistivity q 25 and material constant B 25/85 of the NTC thermistors increase from 4.77 X cm to 4.89 9 10 7 X cm and from 641 to 5085 K, respectively, when the content of Zr, x, changes from 0 to 0.1. The NTC thermistors also show high cyclic stability and ageing resistance. The analysis of impedance spectra reveals that the NTC effect mainly resulted from the grain-boundary contribution, and the conduction mechanisms of the Sn 0.95-x Sb 0.05 Zr x O 2 thermistors combine with the electron-hopping conduction and band conduction.
