Abstract

Most of the supercapacitors reported in literatures showed little or no flexibility in the working temperature around 150°C. However, the supercapacitors are generally exposed under complex system or extreme temperature, such as electric vehicles and extremely cold area. Herein, we successfully fabricated a large-scale robust nanocarbon hybrid film consisting of reduced graphene oxide (rGO), carbon nanotubes (CNTs) and MnO_x nano-flowers with the size up to 550 cm². The mechanical properties of the hybrid films depend on the ratio of CNTs. The supercapacitors prepared with the hybrid films exhibit high flexibility and keep their performances in a temperature range from −20 to 200°C. In addition, the devices display remarkable electrochemical and deformation stability at extreme temperature. This strategy has a potential for the more efficient preparation of flexible electrode materials.
