6 FAQs about [Defocused Laser Flexible Capacitor]

Can a laser be used to produce electrodes of supercapacitors?

Lasers with various combinations of pulse widths and wavelengths may be similarly applicable for producing electrodes of supercapacitors from different kinds of polymers. Depending on these parameters, the beam scanning speed, laser power and number of pulses may be optimized to increase the process throughput.

Can femtosecond lasers be used to make micro-supercapacitors?

Our results present facile fabrication of on-chip micro-supercapacitors that is free of deposition of carbon nanomaterials and photolithographic micro-patterning. We finally comment that our methodology is not limited to use of femtosecond lasers.

Can laser-induced carbonization be used to make flexible micro-supercapacitors?

Furthermore, a focused laser beam can localize the area of carbonization, opening up a new route to achieving direct writing of carbon micro-patterns on polymeric sheets by laser beam scanning. In this report, we introduce the laser-induced carbonization technique for facile fabrication of flexible micro-supercapacitors.

What are flexible supercapacitors?

Evidently, flexible supercapacitors offer a unique combination of conformability and durability, leading to withstand lengthy charge–discharge cycles even at higher temperatures. [11 - 13] Based on the charge storage, there are two distinct subtypes of supercapacitors: 1) electrochemical double-layer capacitors (EDLCs) and 2) pseudo-capacitors.

Can a laser beam be used to create micro-supercapacitor electrodes?

Combined with the carbonization process, these porous carbon structures can be a good candidate for micro-supercapacitor electrodes. Furthermore, a focused laser beam can localize the area of carbonization, opening up a new route to achieving direct writing of carbon micro-patterns on polymeric sheets by laser beam scanning.

Can micro-supercapacitors be used for flexible devices?

The CV response reveals only a moderate degree of change in capacitive characteristics by bending, which is comparable to that of carbon nanotube array-based flexible micro-supercapacitors . This promising mechanical performance of our all solid-state micro-supercapacitors suggests their potential use for flexible devices.
