The field of power storage is using many different devices, from Fuel Cells to Capacitors, most of which use harmful chemicals to provide the storage. One of the newer options for engineers to choose is a supercapacitor, which can hold as much energy as a battery while the power from a capacitor. This new electrical device is often made by very expensive materials and through complicated steps, which can be harmful to the environment. These add large costs to any company looking to create power storage through Supercapacitors. Graphene Oxide (GO) is a unique material with good strength/flexibility, tailorable electrochemical properties, and good sustainability. reduced Graphene Oxide(rGO) is applied as an active electrode material for sensors and flexible energy devices due to its high electric conductivity and large surface area. Compared to the other reduction strategy, laser reduction is a single-step, precise, low cost, and chemical-free processing that can be directly applied on the GO membrane at room temperature in an ambient condition. Through a Laser induced reduction process, a planar micro supercapacitor can be produced by transferring the patterned GO into rGO. The effects of the reduction will be characterized and evaluated using scanning electron microscope (SEM), Fourier Transform Infrared (FTIR) spectroscopy, Raman spectroscopy, X-ray diffraction (XRD)spectroscopy, and two-point probe station. The electrochemical performance of the as patterned and fabricated Micro supercapacitors will be evaluated in this study. This research aims to advance the one step laser induced manufacturing of Graphene Oxide based micro supercapacitors.
