dc.description.abstract | A nanostructured ZnTe-TiO2-C composite is synthesized, via a two-step high-energy mechanical milling process, for use as a new promising anode material in Li-ion batteries (LIBs). X-ray diffraction and X-ray photoelectron spectroscopy results confirm the successful formation of ZnTe alloy and rutile TiO2 phases in the composites using ZnO, Te, Ti, and C as the starting materials. Scanning electron microscopy, transmission electron microscopy, and energy dispersive X-ray spectroscopy mapping measurements further reveal that ZnTe and TiO2 nanocrystals are uniformly dispersed in an amorphous carbon matrix. The electrochemical performances of ZnTe-TiO2-C and other control samples were investigated. Compared to ZnTe-TiO2 and ZnTe-C composites, the ZnTe-TiO2-C nanocomposite exhibits better performance, thereby delivering a high reversible capacity of 561 mAh g(-1) over 100 cycles and high rate capability at a high current density of 5 A g(-1) (79% capacity retention of its capacity at 0.1 A g(-1)). Furthermore, the long-term cyclic performance of ZnTe-TiO2-C at a current density of 0.5 A g(-1) shows excellent reversible capacity of 528 mAh g(-1) after 600 cycles. This improvement can be attributed to the presence of a TiO2-C hybrid matrix, which acts as a buffering matrix that effectively mitigates the large volume changes of active ZnTe during repeated cycling. Overall, the ZnTe-TiO2-C nanocomposite is a potential candidate for high-performance anode materials in LIBs. | - |
