摘要: A novel spherical Sn/SnO2/porous carbon composite anode material was successfully synthesized from activated mesocarbon microbeads (AMCMBs) and SnCl4·5H2O as starting materials by a simple hydrothermal method followed heat treatment. SnO2 dispersed on AMCMB partially reduced into metallic Sn favorable for high capacity. The structure, morphology, electrochemical properties have been studied x-ray diffraction, scanning electron microscopy, performance test. results show the porous supporting matrix surface supports huge volume expansion keeps structural stability of Sn/SnO2 during insertion/extraction process lithium ion. Sn/SnO2/AMCMB sample annealed at 600 °C takes full advantages superiorities carbon, SnO2, exhibits an excellent cycling rate capability. specific capacity is 451 mAh g−1 current density 100 mA after 50 cycles. has large potential application high-performance lithium-ion batteries.
