Nanosized SnO2@BNNSs composites were prepared by the simple and industrializable coprecipitation method. The SnO2 nanoparticles were homogeneous and distributed on BNNSs with diameter at approximately 4-5nm. SnO2@BNNSs@C composite was prepared with glucose as carbon source to improve the electron conductivity. Compared with SnO2 and SnO2@C, the SnO2@BNNSs@C complex has a reversible specific capacity of 490mAh/g after 50 cycles at the current density of 100mA/g, and its efficiency up to 98.8%. The synergistic effect between three components (SnO2, BNNSs, C) is conducive to the improvement of electrochemical performance.
