Planar Patterning Design and Energy Storage Performance Comparison of Laser-Induced Graphene Flexible Supercapacitors.

Laser-induced graphene (LIG) has gained significant attention due to its efficient and rapid production, and ability to create patterned electrodes. However, the operating voltage of LIG supercapacitor (LIG SC) unit devices is relatively low, and the different patterning LIG SC devices show different performances. Additionally, the size of the laser power also has a significant impact on the performance of the device.

Ultraviolet Photothermal Radiation Customized Nitrogen Terminals of TiCT MXene for High-Performance Supercapacitors.

Two-dimensional MXenes have emerged as exceptional electrode materials for supercapacitors (SCs), making them highly attractive for energy storage and conversion applications. However, their electrochemical performance is strongly influenced by surface terminal groups and interlayer spacing. In this study, we introduce an ultraviolet(UV)-induced nitrogen-doping method that employs UV radiation to promote the thermal decomposition of ammonium oxalate while inducing nitrogen-doping.
