Abstract
Abstract Two-dimensional molybdenum disulfide (MoS 2 ) is a promising energy storage material due to its high surface area and unique electronic structure. Free-standing flexible MoS 2 -based electrode is of importance for use in flexible energy storage devices, whereas there are limited reports available. In this work we developed a robust hybrid film, MoS 2 incorporated with highly conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate). This free-standing film possesses excellent mechanical properties with a fracture strength of 18.0 MPa and a Young’s modulus of 2.0 GPa. It can deliver a large volumetric capacitance of 141.4 F cm −3 , a high volumetric energy density of 4.9 mWh cm −3 , and a capacitance retention rate of 98.6% after 5000 charge/discharge cycles. This film has demonstrated its application in an all-solid-state bendable supercapacitor as well.
