The Carbon Nanotube Fibers for Optoelectric Conversion and Energy Storage
Figure 15
(a) Schematic illustration to the structure of all-solid-state, coaxial, and integrated fiber device. The left and right sections correspond to the PC and ES parts, respectively. (b) Schematic diagram shows the circuit connection state in the process of charging and discharging. (c) Charging-discharging curve with a current of 0.1 μA during the discharging process. (d) Galvanostatic charging-discharging curve of the self-charging fiber at different current from 0.1, 0.5, and 1 to 5 μA. (e) Cyclic voltammograms at increasing scan rates from 0.1 to 5 V s−1 [33].
