Abstract
Direct-write printing, as a flexible and adjustable printing method, meets the requirements of graphene ink for printability, and has been widely used in the preparation of extraordinary electrode materials. Herein, the fabrication of three-dimensional graphene electrodes is completed by direct-write printing. The porous microstructure of graphene electrode can be controlled by freezing-casting method, which is uncomplicated, low-cost and can be mass produced. According to the performance test of the graphene electrode, the conductivity of the three-dimensional electrode is measured as 122.6 S/m, and the area capacitance is 30.2 mF/cm2. The porous graphene electrode has excellent electrochemical performance and can play a significant role in printed electronics, which paves the way for exploring high-performance equipment with extended functions.
