Description:
<jats:title>Abstract</jats:title><jats:p>Additively manufactured (AM) supercapacitor platforms are fabricated from bespoke filaments, which are comprised of electro‐conductive graphene (20 wt%) incorporated polylactic acid (80 wt%), via fused deposition modeling and denoted as G/AMEs. The G/AMEs are shown to be capable of acting as a template for the electrodeposition of metals/metal oxides, in particular MoO<jats:sub>2</jats:sub> nanowires (MoO<jats:sub>2</jats:sub>‐G/AMEs), which are subsequently explored as a capacitor within 1 <jats:sc>m</jats:sc> H<jats:sub>2</jats:sub>SO<jats:sub>4</jats:sub>, 1‐butyl‐3‐methylimidazolium hexafluorophosphate, and 1‐butyl‐3‐methylimidazolium tetrafluoroborate. Optimization of the MoO<jats:sub>2</jats:sub>‐G/AMEs demonstrates capacitance up to 1212 F g<jats:sup>–1</jats:sup> when used in a symmetric arrangement. The material science described herein represents a significant enhancement in unlocking AMs potential as a valid manufacturing route for device level capacitance architectures.</jats:p>
