Carbon has a wide variety of allotropic forms that possess a diverse range of properties and is explored in a broad spectrum of applications in many areas of science and technology. Among the various carbon materials, glass-like amorphous carbons obtained by pyrolysis of various polymeric precursors in an inert atmosphere have been used extensively in electrochemical and energy storage applications. By altering the chemical composition of the precursor and tuning pyrolysis conditions, the physicochemical properties of the derived carbon can be tailored. Moreover, geometrical patterning of the precursors and subsequent fabrication of three dimensional (3D) pyrolytic carbon micro- and nanostructures provides substantial advantages for various electrochemical applications. The significantly higher specific surface area of the 3D carbon electrodes potentially provides a larger electrode/electrolyte interface and thereby improved electrochemical behaviour, lower resistivity and higher sensitivity. With common manufacturing approaches, it is impossible to fabricate complex free-standing 3D carbon electrodes with well-defined geometrical structures. Therefore, more facile, cost-effective and innovative fabrication techniques are required to achieve structurally complex and tailorable 3D carbon electrodes for electrochemical and energy storage applications.

The aim of this project is to evaluate the potential of using digital light processing (DLP) 3D-printing technology to fabricate superfine carbon structures, and serve them as electrodes in electrochemical and energy storage applications. The effect of different 3D printing and pyrolysis parameters on the electrochemical performance of the electrodes will be systematically evaluated.
