Abstract
The primary objective of this thesis was to examine in detail the behaviour and electrochemical performance of symmetric supercapacitors made using two different 3D-printing methods (Vat-P and FDM). Two cell types are made in this study, one with metallized Vat-P-printed current collectors, the other with conductive PLA (polylactic acid) FDM-printed current collectors in a similarly designed printed coin cell. In Chapter 3, an array of carbon-based active materials was made and tested in both cell types. Chapter 4 focuses on the FDM printed current collectors, examining how solvent pre-soaking effects the electrochemical performance and cycle life of the 3D-printed supercapacitor cells containing these treated current collectors. Chapter 5 introduces pseudo-capacitive Mn3O4-inverse opal electrodes to the 3D-printed supercapacitor cells and highlights the enhanced performance of these electrodes when composited with conductive nanocarbons.
