A promising class of mixed transition-metal oxides (MTMOs) with stoichiometric or non-stoichiometric ratios has recently received notable attention worldwide. Benefiting from their excellent electrochemical properties, these MTMOs will play a substantial role for low-cost and ecologically responsive energy storage/conversion technologies. In this work, we have developed highly crystalline octahedron 3D-Zn2SnO4 by hydrothermal synthesis and evaluated their application in Li-ion batteries (LIBs). Several characterization techniques have been used to analyze structural, compositional, and morphological features of the material. The highly crystalline octahedron 3D-Zn2SnO4 micro-particle attained a specific discharge capacity of 739 mAh g(-1) with a coulombic efficiency of 99% after 100 cycles at a current density of 100 mA g(-1). These attractive results suggest that 3D-Zn2SnO4 shows good performance as a negative electrode material for high-performance LIBs. (C) 2018 Elsevier B.V. All rights reserved.
