Recent advances in screen printable microsupercapacitors for emerging printed electronics

Screen printing is an advanced manufacturing technology that allows the quick and large-scale manufacture of printed microelectronics, credited in light of its cost-effectiveness, simplicity, and flexibility. However, despite the advantages of screen printing, the practical application in printed microelectronics is still restricted by the limitations of functional inks, including challenges in viscosity control, poor wettability on flexible substrates, limited electrical conductivity, and insufficient mechanical robustness. This review article covers the current breakthroughs in ink composition, examines the problematic features of screen printing for consistent, large-scale applications, and emphasizes the innovations in the developing area of printed microelectronics. The discussion opens with the fundamental principles of screen printing and producing water- and organic-based inks, integrating different binders and solvents. Subsequently, attention has changed to the widespread use of screen printing for manufacturing micro-supercapacitors (MSC) for emerging printed electronics applications. This review concludes with an overview of the current status and impending challenges in screen printing MSC in the plethora of printed electronics. And also inspire new ideas and innovations in this emerging field.
