High performing sodium hybrid capacitor with super-ionic conductor NaTi2(PO4)3 |
초록 |
We have developed a new high performing sodium hybrid capacitor (NHC) using sodium super ionic conductor NaTi2(PO4)3 grown on graphene sheets (GNTP) and capacitor type carbon electrode in an organic electrolyte. The hybrid device works on two charge storage reactions that occurs simultaneously, sodium ion intercalation/deintercalation into GNTP, providing high energy, and adsorption/desorption of anion over the pores of carbon provides high power. A high energy density of 80 Wh kg−1 has been achieved at a specific power of Additionally, the hybrid capacitor retains 32 Wh kg−1 of energy at high specific power of 8 kW kg−1, outperforming lithium hybrid capacitors. An outstanding stability of 90% has been achieved even after 75,000 cycles. The combination of high energy at high power along with high stability emerge them as a suitable candidate for next generation high power devices. |
