摘要：

SiO2 aerogel @ carbon nanotube anchored on graphene sheet (SiO2/CNT/GE) has been produced by a mechanical mixing method. The SiO2 nanoparticle and carbon nanotube are dispersed on graphene sheet. When the current density of the SiO2/CNT/GE material is 120 mA g(-1) for lithium ion semi-battery, the first discharge and charge capacities are 839.3 mA h g(-1) and 303.5 mA h g(-1), respectively. After 200 cycles, its discharge capacity retains 624.3 mA h g(-1). When the SiO2/CNT/GE material is used as a negative electrode and LiMn2O4 as a positive electrode for a full cell, the first discharge capacity is 732 mA h g(-1), and the first coulomb efficiency is 93.18%. After 200 cycles, the discharge capacity can still be maintained at 217.9 mA h g(-1), indicating its potential as a negative electrode material for lithium ion battery.
