H-TiO(2) @MnO(2) //H-TiO(2) @C core-shell nanowires for high performance and flexible asymmetric supercapacitors.
A flexible solid-state asymmetric supercapacitor device with H-TiO(2) @MnO(2)  core-shell NWs as the positive electrode and H-TiO(2) @C core-shell NWs as the negative electrode is developed. This device operates in a 1.8 V voltage window and is able to deliver a high specific capacitance of 139.6 F g(-1)  and maximum volumetric energy density of 0.30 mWh cm(-3)  with excellent cycling performance and good flexibility.
