H-TiO2@MnO2//H-TiO2@C Core-Shell Nanowires for High Performance and Flexible Asymmetric Supercapacitors

A flexible solid‐state asymmetric supercapacitor device with H‐TiO2@MnO2 core–shell NWs as the positive electrode and H‐TiO2@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 m...
