| Abstract Scope |
The application of 3D printing in the field of energy storage is of great practical significance but remains extremely challenging. In this work, we fabricated free-standing electrodes with high performance by applying extrusion-based three-dimensional (3D) printing technology coupled with electrodeposition. The printable ink formulated with graphene oxide renders the printed electrodes excellent conductive skeleton for fast electron transportation, dense poly-pyrrole film was formed on the surface of the framework by electrodeposition method that contributes pseudo-capacitance, therefore, an ultralight heterous electrode with well-maintained structural integrity was prepared. Here, we systematically studied the effect of 3D printing process on the electrochemical performance of the heterogeneous electrodes, finding out the suitable printing formula. The preparation of ultralight electrodes is realized by a simple process, which provides a new idea for the large-scale production of three-dimensional electrodes and is conducive to promoting the application of 3D printing technology in the field of energy storage. |
