摘要：
A novel hybrid Li-ion capacitor has been constructed with a porous NiCo2O4 anode and an activated carbon cathode. The capacitor exhibits an ultrahigh working voltage of 4.5 V, good Ragone performance (39.4 W h Kg(-1), 554 W Kg(-1)) and excellent cycling behavior (no energy loss after 2000 cycles).
