Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Large‐area α‐MnO₂ nanoflower arrays are synthesized by using a facile and template‐free electrochemical deposition on flexible graphite paper. These nanoflower arrays exhibit a high specific capacitance of 314 F g⁻¹ at a current density of 1 A g⁻¹ with remarkable rate capability (61.1 % retention at 40 A g⁻¹) and excellent cycle stability. Furthermore, the fabricated flexible symmetric supercapacitor also displays good performance and flexibility.</p> </abstract>
