The cycling performance of Li-Mn-Ni oxide cathode electrodes in Lithium ion batteries depends on the kinetics of degradation process and thus results in the rise of Impedance Spectroscopy. 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 impedance contribution from the surface formation at the electrode dependent on chemical composition and the structure(FESEM) of the surface. The electrochemical performance of composite electrodes made of pristine material and treated composition of Li-Ni-Mn based cathode materials able to demonstrate the charge discharge graphs and half-cells during cycling.Detailed work demonstrates and highlightens the underlying positive effects of proposed material (Li-Ni-Mn-O) , the cyclic voltammetry and the number of cycles performed from the assembled half cell.
