This work presents the synthesis of LiNi₁Mn₁Co₁O₂ (NMC-111) using the oxalate coprecipitation method, aimed at developing high-voltage lithium-ion button cells. The research focuses on evaluating how variables such as pH, reaction time, stirring, temperature, salt concentration, and the amount of precipitating and chelating agents influence the morphology, structure, and properties of the precursor material. Characterization techniques including FTIR, image analysis with FIJI, and cyclic voltammetry were employed to correlate structural and surface changes with electrochemical performance. The results contribute to a better understanding of the oxalate coprecipitation process and enable the optimization of synthesis conditions to enhance the structural stability and electrochemical performance of NMC cathodes for lithium-ion batteries.
