It gives me great pleasure to have the opportunity to bean Editorial Board Member of Global Journal of Chemical Sciences. This opportunity will enable me to gain more knowledge and communicate with the scientific community all over the world. This will help me to enrich my research quality and help me also to assist the researchers to publish their own work in this journal.
As a Professor of inorganic chemistry and my field of interest is lithium ion batteries, I would like to through the light on the importance of this branch of science. I aim to optimize nano sized energy storage cathode materials for lithium batteries for future electric vehicles and portable equipment applications. Rechargeable batteries play a critical role in today’s world of mobile communications and portable electronics. Furthermore, the age of electric vehicles has begun and improved batteries are necessary to operate these cars as an effort to curb urban pollution. Electric vehicles are sometimes referred to as “zero-emission vehicles” because they produce essentially no pollution from the tailpipe or through fuel evaporation. This is important, for it means that the use of electric vehicles could greatly reduce emissions of carbon monoxide and smog-forming pollutants in cities with dirty air. Electric vehicles are gaining attention as an option for improving air quality and lessening dependence on oil.The lithium-ion battery is the state-of-the-art rechargeable power source. It stores about twice the energy per unit mass or volume of conventional technologies and hence is very attractive. The fundamental physics and chemistry of the current Li-ion battery is based on a process known as “intercalation”; the reversible insertion of guest atoms (like lithium) into host solids (the battery electrode materials). I aim to synthesize nano structural cathode materials that can store more guest atoms per formula weight of host. This will lead to batteries with even higher energy densities and will allow reduction of the size of battery packs to power the same equipment. Nano sized materials are becoming important for electrochemical energy storage, so nanotechnology is expected to improve the performance of three parts of the lithium-ion battery: cathodes, anodes, and separators. The use of nano sized solid-state materials not only improves the power density, but also facilitates Li ions insertion/extraction in/out of the storage materials, which improves the cycle life of Li-ion batteries.
