Abstract
Although the development of high-Nickel is being actively carried out to solve the capacity limitation and the high price of raw cobalt due to the limitation of high voltage use of the existing LiCoO2, the deterioration of the battery characteristics due to the decrease in structural stability and increase of the Ni content. It is an important cause of delaying commercialization. Therefore, in order to increase the high stability of the Ni-rich ternary cathod material LiNi0.6Co0.2Mn0.2O2, precursor Ni0.6Co0.2Mn0.2-x(OH)2/xTiO2 was prepared using a nanosized TiO2 suspension type source for uniform Ti substitution in the precursor. It was mixed with Li2CO3, and after heating, the cathode active material LiNi0.6Co0.2Mn0.2-xTixO2 was synthesized, and the physical properties according to the Ti content were compared. Through FE-SEM and EDS mapping analysis, it was confirmed that a positive electrode active material having a uniform particle size was prepared through Ti-substituted spherical precursor and Particle Size Analyzer and internal density and strength were increased, XRD structure analysis and ICP-MS quantitative analysis confirmed that the capacity was effectively maintained even when the Ti-substituted positive electrode active material was manufactured and charging and discharging were continued at high temperature and high voltage.
