Aims of research The study reported here demonstrates a carbon fibre reinforced polymer composite, which can act as a supercapacitor whilst sustaining mechanical loads. This investigation compares the electrical and mechanical properties of different matrix formulations for structural supercapacitors.

Mechanical properties of the prototype structural composite supercapacitors, in all cases there are the same carbon fibre electrodes on each side of the composite separated by a glass fibre separator. Standard deviations shown in parentheses. vF – reinforcement (CF/GF/CF) content, volume % (vol.%). normalised to vF = 55%.
The flexible composite polymer supercapacitor was used to manufacture soft electronics using printable single-walled carbon nanotubes and an organic liquid aqueous gel as an electrolyte.
Among them, using carbon/carbon composite material as an electrode material is a good method to improve the performance of the electrode material of a supercapacitor.
From Figure 2, the supercapacitor had high energy storage and a long cycling life. Moreover, the specific capacitance of supercapacitors built of composites of NiMnCo ternary oxide and PEDOT-PSS can reach 1234.5 F/g −1 at current densities of 1 A/g −1 and an energy density of 51.9 Wh/kg −1 at power densities of 275 W/kg −1, respectively .
