Investigation of Characteristics of CV Properties in LiMn₂O₄ by Primary Nanoparticle Analysis

Abstract

We have compared the electrochemical properties of LiMn₂O₄ nanoparticle and microparticle electrode without binder and conductive additives. The rate performance of the spinel LiMn₂O₄ is improved with decreasing the size of primary particles, which have been observed by cross-sectional LV-SEM. From the ESR measurements, g-factor has been obtained as 2.0, indicating that the electrons in conduction band of active material act as a charge carrier to enhance the high-rate CV performance.
