Abstract

jats:pWe report the fabrication and electrochemical performance of a flexible thin film supercapacitor with a novel nanostructured composite electrode. The electrode was prepared byjats:italicin situ</jats:italic>coprecipitation of two-dimensional (2D) MnOjats:sub2</jats:sub>nanosheets at room temperature in the presence of carbon nanofibers (CNFs). The highest specific capacitance of 142 F/g was achieved for CNFs-MnOjats:sub2</jats:sub>electrodes in sandwiched assembly with PVA-Hjats:sub4</jats:sub>SiWjats:sub12</jats:sub>Ojats:sub40</jats:sub><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1">mml:mrowmml:mo·</mml:mo></mml:mrow></mml:math>jats:italicn</jats:italic>Hjats:sub2</jats:sub>O polyelectrolyte separator.</jats:p>
