Abstract

The Lithium ion batteries are rechargeable batteries and it is proving to be reliably used system to store electrical energy either in mobile phones or electronic stationaries including Hybrid Electric Vehicles (HEV).Among others Li-Mn-O cathode materials are most attractive and build safe and durable lithium ion batteries with high energy density. In this paper, we present the development and breakthrough of this Lithium rich materials demonstrates to synthesis safety, less toxicity, high power/capacity and low cost nanostructured Li-Mn-O based nano powdered cathode material by sol-gel method using acetate materials as precursors with chelating agent in a stoichiometric ratio. TGA/DTA measurements of the sample in the interval of weight loss regions were taken to identify the decomposition temperature and weight. The XRD analysis of the sample indicates that the synthesized material is monoclinic crystalline in nature. The surface morphology, particle size and elemental analysis of the samples were observed from the SEM and EDAX techniques and the results confirmed the agglomerations of nano particles and as expected composition. The cathode materials are coated on aluminium foil and it is further proceeded to coin the half-cell and it is to be tested by electrochemical work stations like Cyclic Voltammetry, Electrochemical Impedence Spectroscopy, Charge discharge curve and Cycle life behaviour.
