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.
A high-performance flexible and weavable asymmetric fiber-shaped solid-state supercapacitor enhanced by surface modifications of carbon fibers with carbon nanotubes J. Mater. Chem. A, 4 ( 2016), pp. 18164 - 18173
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°.
