1. High Energy Li-ion Batteries
Li-ion batteries cover a significant part in our modern life. All small electronic devices are operated by Li-ion batteries. However, due to the operating voltage of 3.2V to 3.6V, they cannot provide a high specific energy. Thus, there is a great demand for high voltage Li-ion batteries, therefore, fluoride-containing cathode active materials offers a significant contribution to this research area. Novel fluor-containing nano-structured inorganic compounds are to be developed.
2. Organic Radical Battery
Recently cathode active materials used in commercial Li-ion batteries employed inorganic based materials such as LiFePO4, NMC and LiMnO2, etc. However, they not only have advantages but also have some disadvantages on charging times, discharge rates and safety issues. At this point, organic polymer based cathode active materials provide low charging times, high discharge rates and safe batteries. Researchers study on developing organic polymers for using in Li-ion batteries as a cathode active material.
3. Novel Inorganic Catalysts for Li/air Batteries
Li-air batteries present a new future in competing with Li-ion batteries due to the 10-fold specific energy values compared with Li-ion batteries. Nevertheless, they are still under research phase and they have no commercials in the markets. One of the most significant research issue is the development of appropriate catalysts converting oxygen molecule into oxygen molecule-ion and vice-versa. Thus, developing novel catalysts are significant for Li-air batteries. Therefore, novel nano-structured inorganic compounds are a hot topic for implementing them as a catalyst.
4. Synthesis of Biogically Active Dihydrofuran Compounds
The compounds containing dihydrofuronaphthaquinone, furonaphthaquinone and benzofuronaphthaquinone are widely found in nature and constitute a significant part of the biologically active compounds. The synthesis of these compounds is difficult and complex. However, the synthesis of the compounds are accomplished in one step by radical cyclization reaction in the presence of manganese(III) acetate and these compounds show biologically activity such as anti-viral, anti-fungal and anti-histaminic properties.
