Ni₂Mn-layered double oxide electrodes in organic electrolyte based supercapacitors.

ABSTRACT: The development of future mobility (e.g. electric vehicles) requires supercapacitors with high voltage and high energy density. Conventional active carbon-based supercapacitors have almost reached their limit of energy density which is still far below the desired performance. Advanced materials, particularly metal hydroxides/oxides with tailored structure are promising supercapacitor electrodes to push the limit of energy density. To date, research has largely focused on evaluation of these materials in aqueous electrolyte, while this may enable high specific capacitance, it results in low working voltage window and poor cycle stability. Herein, we report the development of Ni₂Mn-layered double oxides (Ni₂Mn-LDOs) as mixed metal oxide-based supercapacitor elect
