Abstract

A high energy hybrid capacitor fabricated from highly porous graphitic carbon and novel electrode material Ni<sub>2</sub>P<sub>2</sub>O<sub>7</sub>delivers a maximum energy density of 65 W h kg<sup>−1</sup>at a power density of 800 W kg<sup>−1</sup>, good rate capability and cycling stability in an aqueous Na-ion based electrolyte.
