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

Abstract

One-dimensional SrSn(OH) 6 nanowires were successfully synthesized through a rapid simple methods 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 precipitationshydrothermal treatment of SrSn(OH) 6 nanowiresswas 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.

Facile synthesis and photocatalytic performance of Mg2SnO4/SnO2 heterostructures

“…It is noteworthy that the polyhedralshaped Mg 2 SnO 4 /SnO 2 nanoparticles exhibit much coarser surface than the cubic nanoparticles. It might be due to the more outward facets providing more ways for the release of H 2 O and the decomposition of Mg 2 SnO 3 during calcining [23].…”

Preparation of nano-sized hard carbon spherule and its electrochemical property

“…Recent years, high capacity batteries have aroused great interest all over the world for the development of portable electronic devices. As a result, many kinds of anode materials, such as Sn, Si, Co 3 O 4 , and SrSnO 3 , have been developed to meet the requirements [1][2][3][4][5][6]. As well-known, Sn and Si have the large theoretical capacities of 994 and 4200 mA h g À1 , respectively.…”

Evolution of the structural and microstructural characteristics of SrSn1−xTixO3 thin films under the influence of the composition, the substrate and the deposition method

“…On the other hand, strontium stannate SrSnO 3 is a perovskite which presents an orthorhombic structure (space group Pbnm [6]) with a great potential for a variety of technological applications, such as capacitors [7], insulating layer for high-temperature superconductor single-flux-quantum circuits [8], lithium-ion batteries [9], photocatalysts [10] and humidity sensors [11].…”
