Purpose and goal
Our ultimate goal is to develop efficient and reliable inkjet printing technology for graphene to enable innovative applications in extensive fields and substantially strengthen Swedish industry. This pre-study project, iEnergy, develops efficient technology for industrial-scale inkjet printing of graphene and explores its feasibility for mass production of supercapacitors.
Results and expected effects
It has been demonstrated that KTH´s graphene inks possess compatible rheology and exhibit excellent jetting performance with Xaar´s industrial-scale printheads. The graphene inks adapted for industrial-scale inkjet printing will strengthen our competitiveness in the market of graphene-based functional inks, enhance our chance to gather more industry actors, and expedite a more rapid growth of the future Swedish graphene-based industry.
Approach and implementation
The project is conducted based on the close collaboration between Royal Institute of Technology (KTH) and XaarJet Sweden AB (Xaar). The partners exchange their knowledge through a workshop. KTH scales up their ink formulation technique to produce graphene inks compatible with industrial-scale inkjet printing and uses them to print all-solid-state graphene-based supercapacitors. Xaar characterizes KTH´s graphene inks and tests their printability (jetting performance) through an industrial-scale printhead (with 126 nozzles).
