英文摘要Dual-ion battery (DIB) has been proposed as a novel energy storage device with the merits of high safety, low cost and environmental friendliness. Herein, we have developed core/shell aluminum@carbon nanospheres (nAl@C) as anode material for DIB. The nanoscale framework is composed of an Al nanosphere and an amorphous carbon outer layer that is conductive and protective, facilitating the formation of a stable SEI film during cycling. Owing to the core-shellstructural design, the nAl@C nanospheres demonstrate significantly enhanced electrochemical performance in a nAl@C-graphite DIB. The DIB exhibites highrate performance as well as superior cycling stability with a capacity of 88 mA h g(-1) with 94.6% capacity retention and high Coulombic efficiency (> 99.5%) after 1000 cycles at a high current rate of 15 C. In addition, the nAl@C-G DIB deliveres an ultrahigh specific energy of 148 W h kg(-1) at a high power density of 3701 W kg(-1), which is much better than most commercial lithium-ion batteries.
