The problems of the large volume change during Li insertion and extraction and poor high-power performance of SnO2-based electrodes should be solved for their practical application. Herein, a novel SnO2/C hybrid triple-type nanosphere, in which a layer of amorphous carbon was sandwiched between the layers of the SnO2 and carbon composite, has been designed and fabricated by a top-down approach. Due to its special structure, this kind of SnO2-based electrode exhibited a considerable capacitive performance, offering a greatly enhanced cycling sta...
