Nature of the Electrochemical Properties of Sulphur Substituted LiMn2O4 Spinel Cathode Material Studied by Electrochemical Impedance Spectroscopy
In this work, nanostructured LiMn₂O₄ (LMO) and LiMn₂O3.99S0.01 (LMOS1) spinel cathode materials were comprehensively investigated in terms of electrochemical properties. For this purpose, electrochemical impedance spectroscopy (EIS) measurements as a function of state of charge (SOC) were conducted on a representative charge and discharge cycle. The changes in the electrochemical performance of...
متن کاملVisualization of ion transport in Nafion using electrochemical strain microscopy.
The electromechanical response of a Nafion membrane immersed in water was probed using electrochemical strain microscopy (ESM) to redistribute protons and measure the resulting local strain that is caused by the movement of protons. We also measured the relaxation of protons from the surface resulting from proton diffusion. Using this technique, we can visualize and analyze the local strain cha...
متن کاملElectrochemical Characteristics of LiMn2O4 (Li/Ni) Cathode Materials
The present study used the Pechini process with a continuous furnace to synthesize LiMn2O4 powders. After heat treatment, the particle size and lattice constant of the LiMn2O4 powder increased. For heat treatment cathode powders (LMO800), due to both the average valence of Mn cations approaching the theoretical value and the higher crystalinity, the discharge capacities are raised significantly...
متن کاملافزایش عملکرد سیکلی ماده کاتدی LiMn2O4 باتری‌های یون- لیتیومی توسط نانو ساختارفسفاتی LiFePO4
In this paper, LiMn2O4 spinel cathode materials have been successfully synthesized by solid-state reaction. Surface of these particles modified by nanocoating of LiFePO4. Synthesized products were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Spectroscopy (EDX). The results of electrochemical tests showed that charge/discharge ca...
