Synthesis and properties of Li2SnO3/polyaniline nanocomposites as negative electrode material for lithium-ion batteries

► Li2SnO3/polyaniline nanocomposite (40-50 nm) was synthesized by micro emulsion polymerization. ► Li2SnO3/PANI exhibits lower initial irreversible capacities than Li2SnO3. ► Its capacity retains 569.2 mAh g−1 after 50 cycles.
