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 capac…
