From: Wearable woven supercapacitor fabrics with high energy density and load-bearing capability
SEM images of (a) the top view and (b) the cross-section view of a carbon fiber thread containing 3000 fibers coated with solid electrolyte. (c) Tensile tests of threads using CF-A0, CF-A1, and CF-A2. (d) Failure pressure of the crossing point in supercapacitor fabrics as a function of electrolyte thickness. In each test, two identical threads with electrolyte coating are overlapped and compressed, and the pressure at which two threads are electrically shorted is recorded as the failure pressure.
