      abstract     = {Herein, we report a new Na-insertion electrode material,
                      Na2Ti9O19, as a potential candidate for Na-ion hybrid
                      capacitors. We study the structural properties of
                      nanostructured Na2Ti9O19, synthesized by a hydrothermal
                      technique, upon electrochemical cycling vs Na. Average and
                      local structures of Na2Ti9O19 are elucidated from neutron
                      Rietveld refinement and pair distribution function (PDF),
                      respectively, to investigate the initial discharge and
                      charge events. Rietveld refinement reveals electrochemical
                      cycling of Na2Ti9O19 is driven by single-phase solid
                      solution reaction during (de)sodiation without any major
                      structural deterioration, keeping the average structure
                      intact. Unit cell volume and lattice evolution on discharge
                      process is inherently related to TiO6 distortion and Na ion
                      perturbations, while the PDF reveals the deviation in the
                      local structure after sodiation. Raman spectroscopy and
                      X-ray photoelectron spectroscopy studies further corroborate
                      the average and local structural behavior derived from
                      neutron diffraction measurements. Also, Na2Ti9O19 shows
                      excellent Na-ion kinetics with a capacitve nature of $86\%$
                      at 1.0 mV s–1, indicating that the material is a good
                      anode candidate for a sodium-ion hybrid capacitor. A full
                      cell hybrid Na-ion capacitor is fabricated by using
                      Na2Ti9O19 as anode and activated porous carbon as cathode,
                      which exhibits excellent electrochemical properties, with a
                      maximum energy density of 54 Wh kg–1 and a maximum power
                      density of 5 kW kg–1. Both structural insights and
                      electrochemical investigation suggest that Na2Ti9O19 is a
                      promising negative electrode for sodium-ion batteries and
                      hybrid capacitors.},
