In the present work, an interconnected sandwich carbon/Si-SiO2/carbon nanospheres composite was prepared by template method and carbon thermal vapor deposition (TVD). The carbon conductive layer can not only efficiently improve the electronic conductivity of Si-based anode, but also play a key role in alleviating the negative effect from huge volume expansion over discharge/charge of Si-based anode. The resulting material delivered a reversible capacity of 1094 mAh/g, and exhibited excellent cycling stability. It kept a reversible capacity of 1050 mAh/g over 200 cycles with a capacity retention of 96%.
The interconnected sandwich carbon/Si-SiO2/carbon nanospheres composite exhibits good battery profile with a reversible capacity of 1094 mAh/g and a reversible capacity of 1050 mAh/g over 200 cycles with a capacity retention of 96%.Figure optionsDownload as PowerPoint slide
