  5. 4. Inkjet Printing of Graphene-based Microsupercapacitors for Miniaturized Energy Storage Applications

    Författare :Szymon Sollami Delekta; Mikael Östling; Jiantong Li; Donald Lupo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; graphene; supercapacitor; microsupercapacitor; energy storage; printed electronics; printing technologies; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Printing technologies are becoming increasingly popular because they enable the large-scale and low-cost production of functional devices with various designs, functions, mechanical properties and materials. Among these technologies, inkjet printing is promising thanks to its direct (mask-free) patterning, non-contact nature, low material waste, resolution down to 10 µm, and compatibility with a broad range of materials and substrates.
