Thesis on supercapacitor

The infrared laser DVD burner causes the reduction and simultaneous exfoliation of graphite oxide and produces isolated graphene monolayers but tangled called "Laser Scribed Graphene" LSG. Two electrodes are sandwiched with an electrolyte layer in the middle. The result is a high density electrochemical capacitor, said supercapacitor.

Download Dissertation Abstract Supercapacitor s have been recognized as unique energy storage devices which have higher energy density than conventional capacitors, and higher power density and longer cycle life than batteries, filling the gap between conventional dielectric capacitors and batteries.

They can release large discharge current instantly. Now supercapacitors have become a hotspot in research, and in many countries other than China, supercapacitors have been successfully used in electric vehicles. We prepared a series of nickel oxide NiO and its composites materials using chemical precipitation method.

By experiments we got the conclusions as follows: We found that the addition of AB can enhance the electricity, cycle reversibility and specific capacitance of NiO.

This is a new progress compared to the literature reports. We studied the effect of different thermal treatment method on the materials. It can be found from examinations that the composite material obtained by second expanded had better properties. It has smaller grain diameter, larger specific surface and better electrochemical performance.

NiO was synthesized by chemical precipitation using nano silicon dioxide SiO2 as carrier. The grain diameter is bigger than the former two materials. It is micron grade and the others are nano grade.

We researched the influence of different addition of SiO2 on final materials. It can be found that the material prepared when the mass ration of SiO2: It has smaller grain diameter, distribute uniformly, smaller polarization, has smaller equivalent series resistance and charge transfers resistance.

In a word, it suits to be used as supercapacitor electrodes materials.Graphene-based Supercapacitors for Energy Storage Applications THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Supercapacitors, also known as ultracapacitors or electrochemical.
