| 英文摘要 | In this work, for the first time, the sodium ion intercalated compound NaTi2(PO4)3has been designed to function as the anode in combination with activated carbon as the cathode to develop a novel aqueous sodium-ion hybrid supercapacitor based on the Na2SO4aqueous electrolyte. Both anode and cathode have been fabricated with a thick (>1 mm) freestanding structure. The as-proposed NaTi2(PO4)3//activated carbon hybrid supercapacitor exhibits a typical supercapacitor-battery behavior. During the galvanostatic charging and discharging process, a linear sloping voltage range from 0 to 0.8 V corresponding to supercapacitor has been observed and an obvious voltage plateau in the range of 0.8–1.6 V could be related with the battery characterization. The hybrid supercapacitor thus brings a much high energy density over conventional supercapacitor based on activated carbon electrode. The NaTi2(PO4)3//activated carbon system shows a discharge capacity of 27.5 mAh g−1with an average working voltage of 1.15 V, corresponding to a high energy density of 31.6 Wh kg−1at a power density of 23 W kg−1based on the total weight of active electrode materials. It also exhibits excellent cycling behavior with less than 11.7% capacitance loss after 2000 cycles at current density of 200 mA g−1. The cell delivers a relatively high power ability of 420 W kg−1with the energy density of 15.5 Wh kg−1. © 2017 |
