New Advances in Studies on Flexible and Miniaturized Supercapacitors of Dalian Institute of Chemical Physics, Chinese Academy of Sciences

Recently, the team of Wu Zhongshu, a researcher from DNZ21T3 group, Institute of Advanced 2D Materials and Energy Devices, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, has made new progresses in the research of flexible and miniaturized graphene based supercapacitors and successfully obtained 2D Thiophene nanosheets and graphene laminated composite films, and applied to high performance, flexible, miniaturized supercapacitors. Relevant research results published in the "Advanced Materials" magazine (DOI: 10.1002 / adma.201602960). In recent years, with the highly integrated, lightweight portable, wearable, implantable and other new concepts, especially the concept of flexible electronic products constantly put forward, there is an urgent need to develop highly compatible with its high energy density, Flexible, functional integration of micro-energy storage devices. To achieve this goal, the team successfully synthesized graphene based high power planar micro supercapacitors by combining methane plasma reduction and photolithographic micromachining in a previous study (DOI: 10.1038 / ncomms3487). The graphene films doped with nitrogen and boron co-doped by layer-by-layer self-assembled graphene oxide and polylysine with intercalation of boric acid were applied to micro-supercapacitors (Acv. Mater. 2014, DOI: 10.1002 / adma.201401228); high density, high conductivity polymer / graphene, activated graphene / graphene thin film materials are prepared by alternate stacking method, Micro Flexible Supercapacitor (Adv. Mater. 2015, DOI: 10.1002 / adma.201501643); Graphene conductive polymer film is prepared by spray coating method, which is used in ultra-thin, printable and ultra- Capacitors (Adv. Mater. 2015, DOI: 10.1002 / adma.201501208). These flexible, miniaturized supercapacitors represent important applications for future electronics (Natl Sci. Rev. 2014, DOI: 10.1093 / nsr / nwt003). This work has been funded by the National Youth Thousand Talents Program, the National Key Research and Development Program, the National Natural Science Foundation of China and the Liaoning Provincial Natural Science Foundation.
