Abstract

Recent year’s energy, water and health care are one of the important areas research carried out by worldwide researchers. Among all energy storage, Lithium Ion Batteries (LIBs) are extensively used in the present-day portable electronic devices and high-power applications like back-up power supplies and electric/hybrid electric vehicles. The commercial LIBs consist of layer-type lithium cobalt oxide, spinel LiMn2O4 or LiFePO4 as the cathode and graphite or Li4Ti5O12 as the anode material and a non-aqueous Li- ion conducting solution or immobilized gel-polymer are used as an electrolyte. LIBs need to satisfy several additional criteria, such as safety, toxicity, low cost and long cycle life. To understand reaction mechanisms advanced analytical techniques are needed. In my presentation, I will summarize our group studies on functional materials synthesis by molten salt synthesis, graphenothermal reduction and other facile chemical methods on various oxides, nitride materials and novel metal organic frame work cathode materials will be discussed. The functional materials characterized by various analytical techniques such as Rietveld refinement X-ray diffraction, X-ray absorption fine structure, X-ray photoelectron spectroscopy, SEM, TEM, density and BET surface area methods and cyclic voltammetry, galvanostatic cycling and electrochemical impedance spectroscopy techniques. I will discuss the advantages of morphology, nano/submicron size, matrix elements on capacity values and average charge-discharge voltages and its electrochemical performances and reaction mechanisms.
