The Quantitative Analyses of the Dissolved Manganese in the Electrolyte of Li/LiMn2O4Cell Using by Ion Chromatography

The reason for the capacity fading at high temperature is believed to be due to factors such as, i) the decomposition of electrolyte at the high voltage region; ii) the particle fracture due to repeated cycling. The dissolution of manganese during cycling is believed to take place when the cathode encounters low discharge voltage where the presence of large amount of Mn
