A novel approach to fabricate supercapacitors (SCs) via vapor printing, specifically oxidative chemical deposition (oCVD), is demonstrated. Compared stacking multiple layers into a SC, this method enables the monolithic integration of all components single‐sheet substrate, minimizing inactive materials and eliminating possibility multilayer delamination.
