By employing 3D current collectors, hybrid coplanar microsupercapacitors are fabricated. These devices show excellent energy density of 200 μW h cm−2 compared to the state-of-the-art microsupercapacitors (1–40 μW h cm−2), and superior power density (4.4 mW cm−2) compared to thin film batteries and microbatteries at comparable energy density.
