摘要：

Inspired by nature, both high-performance Si/C and activated carbon (AC) energy storage materials with a hierarchically biomimetic structure can be prepared from rice husks (RHs), and further serve as promising anode and cathode materials for hybrid lithium-ion capacitors (LICs), respectively. Benefitting from the high capacity and good rate and cycling performances of the Si/C anode material and RH-derived AC (RAC) cathode material, the designed Si/C vertical bar vertical bar RAC LICs give a high energy density of 227 W h kg(-1) at a power density of 1146 W kg(-1), and similar to 181 W h kg(-1) can still be retained even at an ultra-high power density of similar to 32 595 W kg(-1). Furthermore, the RH-derived LICs also show a long-term cycling stability (16 000 cycles at similar to 16 800 W kg(-1)).
