High-Energy-Density TiO2-Coated LiNi0.9Mn0.05Co0.05O2 (NMC 955) as Cathode for Lithium-Ion Batteries

Year: 2025

Type: article

Abstract: Along with the rapid development of technology in this modern era, batteries have a significant role, used as energy storage devices. Lithium-ion batteries have reliable characteristics as energy sources for electronic devices and electric vehicles. Nickel Manganese Cobalt (NMC) is claimed to be the best cathode for high-energy-density lithium-ion batteries. This study aims to analyze the effect of the addition of TiO2 nanoparticles as a coating material with variations of 1, 3, and 5 wt.% on the morphology and electrochemical performance of LiNi0.9Mn0.05Co0.05O2 (NMC 955). The coating process with the addition of TiO2 through ball milling method at a speed of 600 rpm for 1 minute and 1000 rpm for 60 minutes. The results obtained are an increase in particle diameter in the 5 wt.% variation with particle size in the range from 0.1 to 0.5 μm. NMC 955 TiO2 1% has the highest specific capacity of 168 mAh g-1 at 0.5 C. It is indicated that the process of adding TiO2 coating on NMC 955, can improve the electrochemical performance in terms of specific capacity compared to NMC 955 without TiO2 coating.
