Here, the porous ruthenium oxide/multi-walled carbon nanocomposite (RuO2/MWCNT) was prepared using a facile precipitation method. The RuO2/MWCNT showed high specific capacity, outstanding rate performance and long cycling stability under a Li-ion organic electrolyte. Thus, advanced Li-ion hybrid capacitors (LIHCs) were successfully constructed with RuO2/MWCNT anode and activated ployaniline derived carbon (APDC) cathode under a Li-ion organic electrolyte. The LIHCs exhibited a highest energy density of 146 Wh kg(-1) and a highest power densities of 33 kW kg(-1), with excellent cyclic stability (similar to 100% at 2.0 A g(-1) after 15,000 cycles), which exhibited better performance than other LIHCs systems.
