Laser energy storage design specifications

What are the processing parameters during laser heating and transient cooling?

Key processing parameters during the laser heating and transient cooling include the use of nanosecond pulse laser irradiation with a light intensity above 10 8 W cm −2 and an energy density exceeding 10 J cm −2, which induce plasma formation and promote the diffusion and incorporation of nitrogen into molten titanium.

What is laser-processed graphene based supercapacitors?

Laser-processed graphene-based supercapacitors outperform conventional supercapacitors in terms of volumetric energy performance. A laser machine can shape electrode arrays and reduce the electro-sprayed GO thin layer into laser-processed graphene (LPG) by adjusting the output laser power 27.

How can a large-area processable light source improve optical energy density?

To address this issue, large-area processable light sources (e.g., line beam lasers, and flash lamps) along with optical beam shaping technologies can be introduced to enable required optical energy density over broad surfaces without sacrificing process quality and precision.

Does lig/2%CNTs based SC device have a high energy storage capacity?

The energy density of the LIG/2%CNTs based SC device is measured as 6.5 μWh cm −2 at a corresponding power density of 0.219 mW cm −2 which is relatively higher than what is mainly reported 42 in the literature 40. This suggests that the device has a high energy storage capacity per unit area.

Why do we need a nanostructured energy storage device?

Recent advances and challenges in creating nanostructured and nano-engineered materials have emphasized the need for energy storage devices with mechanical robustness, multifunctional resilience, adaptability, and integration to enable more attractive, lightweight, compact, and intelligent designs 10, 11, 12, 13.

What is the surface roughness of Lig based on laser treatment?

AFM analysis revealed a surface roughness of 2.03 µm for LIG due to laser treatment. SEM images displayed compact, dense, and porous surface morphology. XRD analysis confirmed the presence of graphene and graphene oxide, which was further supported by energy-dispersive X-ray spectroscopy (EDX) data.
