英文摘要: Carbon-coated SnO2 nanotube networks were fabricated by a simple dip-coating process and subsequent CVD growth. The as-prepared material, worked as a binder-free anode for lithium ion battery, delivers a reversible capacity of 653 mAh g(-1) after 50 cycles at a current density of 400 mA g(-1). The enhanced electrochemical performance can be ascribed to the following factors: (1) The network nanostructure can accommodate the volume changes of the SnO2 nanoparticles. (2) The porous walls of the prepared nanotubes increase the electrode-electrolyte contact area, shorten the distance of diffusion and provide more reaction sites for lithium ions. (3) The carbon coating increases the conductivity and hinders the aggregation of the SnO2 nanoparticles during the insertion/extraction processes of lithium ions. (C) 2015 Elsevier B.V.
