Abstract

We report a high-performance flexible in-plane micro-supercapacitor (MSC) consisting of a graphene/laser-induced graphene hybrid film which was prepared on both sides of a polyimide (PI) film with slit-shaped through holes. The front and back side carbon electrodes were electrochemically connected by through holes filled with a polymer electrolyte. Such an in-plane MSC was prepared by laser annealing and ablation of a graphene/polyamide hybrid coating on a PI film, where the laser annealing of a hybrid coating film was conducted by a CW 445 nm diode laser and slit-shaped through holes were prepared by laser ablation using a pulse fiber laser.
