As the industry develops, sustainable energy sources such as fossil fuel and lithium-ion battery (LIB) is in the spotlight. Especially, various studies on the safety and capacity of LIBs are of special interest nowadays. For battery performance, there are various factors such as each component, structure, electrode density and even dispersion of the material is one of the important factors. However, there are not many new methods for the ‘processing to prepare LIB’. CNT is a conductor material in both anode and cathode, which have high electrical/thermal conductivity but normally difficult to dispersion because of their strong Van der Waals attraction between the tubes and π–π interactions. In this study, to enhance the dispersion of CNT, the electrode slurry was dispersed using a three-roll mill beyond the conventional method. NCM811-CNT cathode slurry was dispersed to prepare LIB cells, and the electrochemical performances were compared with NCM811-Super P cell.
