Studies on the Change of Lithium Ion Battery Performance According to Length and Type of Surfactant on the Surface of Manganese Oxide Nanoparticles Prepared by Reverse Micelle Method

In order to accurately analyze how the surfactant attached on the surface of the nanoparticles affects the catalytic activity, all other experimental conditions should be maintained except the surfactant. In this study, we control the hydrocarbon chain length of the alkylamine and carboxylic acid on the surface of manganese oxide (Mn3O4) nanoparticles while keeping their size and shape using a reverse micelle method. Despite the use of various lengths of surfactants, the size and shape of the synthesized nanoparticles remain virtually unchanged. After the mild heattreatment, they have different secondary particle morphologies even though the nano particles are preserved. Those prepared nanoparticles exhibit the characteristics voltage behavior under the galvanostatic charge and discharge. The obtained electrochemical performances are influenced by the surfactants. A coin cell having Mn3O4 nanoparticles coated by hexanoic acid and hexylamine shows the highest capacity than the other samples. Open image in new window
