Presently, most asymmetric capacitors are fabricated by following two combinations: (i) a capacitive carbon electrode and a pseudocapacitive electrode, and (ii) a capacitive electrode and a lithium insertion electrode.
Fiber-shaped supercapacitors (FSCs) have excellent electrochemical properties and flexibility, can function in the forms of individual fibers or integrated textiles, and thus are the most promising energy storage devices for future portable and wearable electronics.
The capacitance of a FSC can be considered as the total capacitance of two electrodes connected in series, and can be expressed as: (1) 1 C = 1 C + + 1 C − where C + and C − represent the capacitance of positive and negative electrodes, respectively.
At present, both conventional supercapacitors and fiber-based ones are usually assembled by two isolated electrodes full of electrolyte. Two twisted fiber electrodes not only increase the contact resistance but also make the production process complicated, limiting the large-scale integration in the recent development of portable electronic.

For example, a coaxial FSC with CNT coated CMF bundle as the core electrode, and a carbon nanofiber film as the outer electrode, separated by a Celgard 3501 paper and PVA-H 3 PO 4 gel electrolyte, demonstrated a C S of 86.8 mF/cm 2 and an energy density of up to 9.8 µWh/cm 2. The capacitive performance were stable upon bending from 0° to 180°.

With respect to FSCs, the key issue is to fabricate fiber-shaped electrodes (FSEs) and assemble all components into a fiber-shape device. FSEs can be realized by making current collectors and active materials directly into a fiber form or cladding them around existing fibers. FSCs are assembled primarily in four types of structures ...
The simplest capacitor architecture involves two planar parallel electrodes separated by an insulating material. In that case, the capacitance is given by C ¼ e dA t; (1) where e d is the absolute permittivity of the dielectric layer and t its thickness, while A is the area over which the elec-trodes are facing. Large capacitance is, therefore ...

A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum, and, in that case, a …
