Summary: Composite structural supercapacitors (SSC) were manufactured using aerospace-grade composite materials and CNT mat electrodes. A new design methodology was explored where the supercapacitor electrolyte was localized within the composite structure, achieving good electrochemical performance within the active region, whilst maintaining excellent mechanical performance elsewhere. The morphology of these localized SSC designs was characterized and found to be directly correlated with both electrochemical and mechanical performance. One configuration using an ionogel with an ionic liquid electrolyte achieved high energy density and corresponding short beam shear strength, while another configuration with only an ionic liquid electrolyte also achieved high energy density and shear strength. Both configurations provide a combined energy and strength superior to previous results in the literature for composite SSCs.

In this study, a series of CuFexMn2-xO4-MWCNT-y spinel composites were successfully synthesized via a solvothermal method. The CuFe0.4Mn1.6O4-MWCNT-3 modified electrode demonstrated the highest specific capacitance of 656.7 F.g(-1) at a current density of 1.0 A.g(-1), with good cycling stability of 80.6% capacitance retention after 5000 cycles at a current density of 8.0 A.g(-1). Moreover, the CuFe0.4Mn1.6O4-MWCNT-3//activated carbon (AC) asymmetric supercapacitor exhibited a higher capacitance of 104.0 F.g(-1) at 1.0 A.g(-1), with a maximum energy density of 30.43 Wh.kg(-1) and power density of 3500 W.kg(-1).

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
