主　　题：SnO_(2) nanotubes N-doped carbon anode Li-ion battery 

摘      要：Tin dioxide nanotubes with N-doped carbon layer(SnO_(2)/N-C NTs)were synthesized through a MoO3 nanorod-based sacrificial template method,dopamine polymerization and calcination *** to the Li-ion battery,SnO_(2)/N-C NTs exhibited excellent electrochemical properties,with a first discharge capacity of 1722.3 mAh·g^(−1)at 0.1 A·g^(−1)and a high capacity of 1369.3 mAh·g^(−1)over 100 *** superior electrochemical performance is ascribed to the N-doped carbon layer and tubular structure,which effectively improves the electrical conductivity of the composites,accelerates the migration of Li+and electrons,and alleviates the volume change of the anode to a certain extent.
