ABSTRACT

Lithium-ion battery (LiB) is one of the special issues on nowadays and diverse researches to develop LiB with better performances have been carried out so far, especially, regarding improved properties of each component such as cathode, anode, separator and electrolyte. However, there are limited information on ‘processing’ to prepare each component, and especially fabrication of cathode is strongly dependent on thinky mixer to realize homogeneous dispersion of active materials and conductors in binders. Herein, we report on preparation of LiNi0.8Co0.1Mn0.1O2 (NCM811) based cathode materials with different carbon conductors (CNT and carbon black) using homogenizer and three-roll milling method. These processes are turned out perfect alternative to prepare cathode electrode. LiB cells were assembled using the dispersed electrode slurry and the performance of a cell was electrochemically stable, even in the case of a CNT conductor, which is normally difficult to make perfect dispersion because of its strong Van der Waals attraction between the tubes and π–π interactions.
