Abstract:
A novel hybrid nanocomposite (HNC) material consisting of Sn, SnO, and SnO 2 was successfully synthesized via a modified hydrothermal technique using urea and SnCl 2 as the precursors. The Sn/SnO/SnO 2 ratio and the structure of the HNC, which can easily be controlled by varying the concentration of the SnCl 2 salt, greatly influence the electrochemical properties of the HNC electrodes when applied as lithium-ion battery anode materials. The highest electrochemical performance was achieved when the concentration of SnCl 2 was 22.5 × 10 −3 M, denoted as sample M3. For instance, the M3 electrode delivered a reversible capacity of 1056 mA h g −1 at 0.1 A g −1 after 100 cycles. Its impressive electrochemical performance was achieved due to the nano-size of Sn/SnO/SnO 2 particles, the highly reversible conversion reaction between the tin oxides and Li 2 O, and a suitable ratio of the components in the M3 sample. This synergistic effect can maintain the stability of the electrode structure and improve the pseudo-capacitance process, leading to excellent Li-ion storage and highly durable cycling of the HNCs.
