Supercapacitors, with the merits of both capacitors for safe and fast charge and batteries for high energy storage have drawn tremendous attention. Recently, laser scribed graphene has been increasingly studied for supercapacitor applications due to its unique properties, such as flexible fabrication, large surface area and high electrical conductivity. With the laser direct writing process, graphene can be directly fabricated and patterned as the supercapacitor electrodes. In this review, facile laser direct writing methods for graphene were firstly summarized. Various precursors, mainly graphene oxide and polyimide were employed for laser scribed graphene and the modifications of graphene properties were also discussed. This laser scribed graphene was applied for electrochemical double-layer capacitors, pseudo-capacitors and hybrid supercapacitors. Diverse strategies including doping, composite materials and pattern design were utilized to enhance the electrochemical performances of supercapacitors. Featured supercapacitors with excellent flexible, ultrafinestructured and integrated functions were also reviewed.

“…As per Equation (1), it is clear that the light absorption coefficient of material depends on both the light wavelength and extinction coefficient. The laser radiation intensity within an examined material can be described by the empirical Beer’s law Equation (2) [ 220 , 221 ].

where I (z) is the laser radiation intensity within materials at a vary depth (z) , measured from the material surface, R is coefficient of light reflection from material surface, and I 0 is intensity of incident laser radiation.…”

The three-dimensional molded interconnected device (3D-MID) has received considerable attention because of the growing demand for greater functionality and miniaturization of electronic parts. Polymer based composite are the primary choice to be used as substrate. These materials enable flexibility in production from macro to micro-MID products, high fracture toughness when subjected to mechanical loading, and they are lightweight. This survey proposes a detailed review of different types of 3D-MID modules, also presents the requirement criteria for manufacture a polymer substrate and the main surface modification techniques used to enhance the polymer substrate. The findings presented here allow to fundamentally understand the concept of 3D-MID, which can be used to manufacture a novel polymer composite substrate.

Carbon (sp3)‐on‐carbon (sp2) materials have the potential to revolutionize fields such as energy storage and microelectronics. However, the rational engineering and printing of carbon‐on‐carbon materials on flexible substrates remains a challenge in wearable electronics technology. This study demonstrates the scalable fabrication of flexible laser‐induced graphene (LIG)‐boron doped diamond nanowall (BDNW) hybrid nanostructures for microsupercapacitors. Direct laser writing on polyimide film is tuned by the presence of BDNW powder where an appreciable absorbance of the BDNWs at the CO2 laser wavelength enhances the local film temperature. The thermal shock due to laser irradiation produces graphitized and amorphous carbon at the diamond grain boundaries which increases the thermal and charge transfer capacity between the LIG–diamond interfaces. The samples are further treated with O2 plasma to tune the wettability or to improve the microsupercapacitor device performance. The outstanding electrical characteristics of graphene, exceptional electrochemical stability of diamond, and essential contributions of oxygen‐containing groups result in a remarkable charge storage capacity (18 mF cm−2 @ 10 mV s−1) and cyclic stability (98% retention after 10 000 cycles) outperforming most state‐of‐the‐art LIG‐based supercapacitors. Furthermore, despite extreme mechanical stress, these microsupercapacitors maintain their outstanding electrochemical properties, thus holding promise for high‐power, flexible/wearable electronics.
