Rapid Synthesis of Single-Crystalline SrSn(OH)₆ Nanowires and the Performance of SrSnO₃ Nanorods Used as Anode Materials for Li-Ion Battery

This is the authors' abstract. We don't add key points for this paper.

One-dimensional SrSn(OH) 6 nanowires were successfully synthesized through a rapid simple method—sonochemical synthesis at room temperature without using any templates or surfactants. The growth mechanism has been proposed, and the reaction conditions were carefully investigated. The experimental results revealed that both the ultrasound irradiation and the presence of Na 2 CO 3 in the synthetic process had an impact on the fast formation of the SrSn(OH) 6 nanowires. Moreover, a subsequent precipitation—hydrothermal treatment of SrSn(OH) 6 nanowires—was conducted in ethanol at 180 °C for 8 h in order to improve their crystallinity and thermal stalibity. SrSnO 3 nanorods were converted by calcination of the hydrothermally treated SrSn(OH) 6 nanowires at 700 °C for 3 h in air. In particular, it was the first attempt to test the electrochemical properties of the SrSnO 3 products as anode in a Li ion battery. The resulting SrSnO 3 nanorods exhibited a better cyclability over 50 cycles with a reversible lithium storage capacity of 200 mA h g −1 than that of SrSnO 3 nanoparticles.
