Efficient energy storage systems are essential in order to increase energy efficiency, improve economic efficiency and reduce environmental impact of mobile and stationary equipment, particularly, in modern transport and energy technologies. Current global economic and technological development has significantly increased the demand for suitable solutions for efficient and temporary energy storage of high-voltage electricity. Long-life supercapacitors are the key element in short-term energy storage systems. At the moment, available solutions related to the high-voltage accumulation are based on prism supercapacitors. However, such equipment is expensive, unreliable and unsafe. While implementation of widespread high-voltage energy storage systems based on supercapacitors using current technologies is not feasible. Alternatively, the project proposes highly reliable, strong and environmentally friendly solid high-voltage supercapacitors that are based on new materials and advanced production technology. These supercapacitors are innovative, scalable, and low-cost and satisfy the technological requirements for efficient energy storage.
LEI activities in the Project
- To perform the effective surface area measurement of graphite substrate and NiO film deposited on the graphite substrate using absorption methods and evaluate application of such structure for production of supercapacitors.
- To deposit nanocrystalline NiO thin films on the graphite substrates using magnetron sputtering technique.
- Comprehensive evaluation of the system where high quality graphite (GR-280) is used as a substrate and nanocrystalline NiO thin films are used as electrochemically active substance.
- To investigate the influence of substrates on the capacity characteristics of obtained supercapacitors.
- To utilize existing magnetron sputtering system (PVD-75) for synthesis of nanocrystalline NiO thin films on the graphite substrates (GR-280).
- To synthesize NiO thin films.
- To investigate obtained films using:
X-ray diffraction technique (DRON UM-1) for microstructure analysis.
Scanning electron microscope (JSM 5600) and atomic force microscope (NT-206) for surface morphology analysis.
Surface resistivity measurement using four-probe method (JANDEL Universal inst.).
Effective surface area measurement using absorption methods.
- To investigate electrical properties of designed capacitors.
- To summarize the obtained results.
According to the achieved results of this research, it is expected to find cheaper substrates. Moreover, NiO thin films could be used for production of commercial supercapacitors.
