Abstract

The nanocomposites Li ₂ SnO ₃ /polyaniline (Li ₂ SnO ₃ /PANI) have been synthesized by a micro emulsion polymerization method. The structure, morphology and electrochemical properties of the as-prepared materials are characterized by XRD, FTIR, Raman, XPS, TGA, TEM and electrochemical measurements. Results show that Li ₂ SnO ₃ /PANI nanocomposites are composed of uniform and blocky nano-sized particles (40-50 nm) with clear lattice fringes. Electrochemical measurement suggests that Li ₂ SnO ₃ /PANI exhibits better cycling properties and lower initial irreversible capacities than Li ₂ SnO ₃ as negative electrodes materials for lithium-ion batteries. At a current density of 60 mA g ^-1 in the voltage about 0.05-2.0 V, the initial irreversible capacity of Li ₂ SnO ₃ /PANI is 563 mAh g ^-1 while it is 687.5 mAh g ^-1 to Li ₂ SnO ₃ . The capacity retained of Li ₂ SnO ₃ /PANI (569.2 mAh g ^-1 ) is higher than that of Li ₂ SnO ₃ (510.2 mAh g ^-1 ) after 50 cycles. The PANI in the Li ₂ SnO ₃ /PANI nanocomposites can buffer the released stress caused by the drastic volume variation during the alloying/de-alloying process of Li-Sn.
