Authors: Yonas Tesfamhret<\/span>, Erik Berg and Reza Younesi Abstract<\/strong><\/p>\n\n\n\n Mn dissolution is known as a major degradation mechanism for LiMn2O4 (LMO) cathodes. Herein, we used atomic layer deposition (ALD) method to form a surface coating of Al2O3 on LMO particles. The uniform and thickness controlled coating improves cycling performance by preventing electrolyte\/electrode interfacial reactions and reduces the surface dissolution of Mn-ions into the electrolyte [1]. LiFePO4 (LFP) is chosen as the counter electrode as opposed to e.g. Li-metal or graphite. Using a high average potential counter electrode restricts the reduction of Mn-ions on the surface of the anode. Inductively coupled plasma optical emission spectroscopy (ICP-OES) based ex situ method is developed for determination of Mn-ions dissolved in to the electrolyte solution.
