SnO2 nanotubes with N-doped carbon coating for advanced Li-ion battery anodes
Tin dioxide nanotubes with N-doped carbon layer (SnO2/N-C NTs) were synthesized through a MoO3 nanorod-based sacrificial template method, dopamine polymerization and calcination process. Applied to the Li-ion battery, SnO2/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 cycles. The 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.
