Abstract

The GNS/Li₂SnO₃/PPY ternary composites were synthesized by a deoxidation technique. The soft polymer matrix and flexible graphene provide a dual buffering structure for Li₂SnO₃ which synergistic leads to improved stability, enhanced electric conductivity and better electrochemical performance. The GNS/Li₂SnO ₃/PPY composites tested as anode materials for lithium ion batteries exhibit a high reversible capacity of 699.4 mAh/g over 30 cycles, which is much better than that of pure Li₂SnO₃, PPY/Li ₂SnO₃ and GNS/Li₂SnO₃ composites.
