From: Wearable woven supercapacitor fabrics with high energy density and load-bearing capability
(a) A photo of a load bearing supercapacitor fabric with the size of 2.5 cm × 2.5 cm. Cyclic voltammetry (CV) curves of the supercapacitor fabric at (b) lower scan rates and (c) higher scan rates with current normalized to the total weight of all carbon fiber threads (~25 mg). (d) Galvanostatic charge–discharge curves of the device under various current densities (normalized to the total weight of all carbon fiber threads). (e) Nyquist plots of the impedances of the woven devices using CF-A0 and CF-A2 with the frequency range from 0.01 to 100k Hz. (f) Capacitance retention of the device using CF-A2 during 10,000 charge/discharge cycling tests.
