Electrochemical capacitance properties of pre-sodiated manganese oxide for aqueous Na-ion supercapacitors.

ABSTRACT: Mn-based oxides are widely investigated as electrode materials for electrochemical supercapacitors, because of their high specific capacitance in addition to the high abundance, low cost, and environmental friendliness of Mn. The pre-insertion of alkali metal ions is found to improve the capacitance properties of MnO₂. While the capacitance properties of MnO₂, Mn₂O₃, P2-Na_0.5MnO₂, and O3-NaMnO₂etc. are reported, there is no report yet on the capacitive performance of P2-Na_2/3MnO₂, which has already been studied as a potential positive electrode material for Na-ion batteries. In this work, we have synthesized sodiated manganese oxide, P2-Na_2/3MnO₂ by a hydrothermal
