Hybrid supercapacitor with nano-TiP2O7 as intercalation electrode

---

Abstract.
Nano-size (≤100 nm) TiP2O7 is prepared by the urea assisted combustion synthesis, at 450 and 900 ◦C. The
compound is characterized by powder X-ray diffraction, Rietveld refinement, high resolution transmission
electron microscopy and surface area methods. Lithium cycling properties by way of galvanostatic
cycling and cyclic voltammetry (CV) showed a reversible and stable capacity of 60 (±3) mAh g−1 (0.5 mole
of Li) up to 100 cycles, when cycled at 15 mA g−1 between 2–3.4 V vs. Li. Non-aqueous hybrid supercapacitor,
TiP2O7 (as anode) and activated carbon (AC) (as cathode) has been studied by galvanostatic cycling and
CV in the range, 0–3 V at 31 mA g−1 and exhibited a specific discharge capacitance of 29 (±1) F g−1stable in
the range, 100–500 cycles. The Ragone plot shows a deliverable maximum of 13 Wh kg−1 and 371 W kg−1
energy and power density, respectively.

Keywords: Hybrid supercapacitor, Lithium ion battery, TiP2O7, Activated carbon
