Abstract

Abstract: Material Nano-genesis has gradually obtained more technical feedback and support in the study of lithium batteries, but problems such as volume expansion still need in-depth study. In this paper, SnO2 –TiO2 –CNS ternary composites were prepared by hydrothermal method and ball milling. Depending on the layered structure, the SnO2 –TiO2 nanoparticles are uniformly attached to carbon nanosheets. It is noteworthy that the volume variation of SnO2 was alleviated by mixed TiO2 and CNS, thus generating a wider space to move around for the lithium ion during the conduction process. The STC was tested for 100 cycles at 0.2 Ag -1 and the capacity was achieved 1046.1 mAhg −1 . At 1.0 Ag -1, the capacity of STC can attain 1443.3 mAhg −1 after 1000 cycles. Then, the SEM image of the recovered electrode material was measured, and it was observed that the SnO2 –TiO2 –CNS composite remained stable.
