Compared with the supercapacitors using liquid electrolyte, all-solid state supercapacitors have many advantages such as lightweight, high flexibility, high safety and environmentally benign nature, which are suitable for flexible and portable electronics. All-solid-state flexible supercapacitors were fabricated through the easy assembly of graphene thin films (as electrode) and crosslinked PEO-PPO block copolymer electrolyte membranes (as electrolyte and separator), which were prepared from triethoxysilane-endcapped PEO-PPO block copolymer precursors. These flexible supercapacitors showed a stable electrochemical response up to 3 V operating voltage and were capable of yielding a high specific capacitance of 71.8 F/g, and extraordinary mechanical flexibility. |
