Abstract
This study was conducted to realize densely packed negative electrode plates for lithium ion secondary batteries through kneading and dispersion process. Several kinds of pastes with different viscosity were made by controlling the amount or concentration of thickener added to them and the relationship was examined between the viscosity of those pastes and the films made from them. Graphite was chosen as the negative electrode material. Films were made from each pastes containing graphite particles of certain diameter or mixture of graphite particles of different diameters. Then it was studied how the distribution of particle diameter affected on the film density. As a result, it was found that the mixture of graphite particles of different diameters could make densely packed film. It was confirmed from SEM photographs that the surface and the cross section of the film were both densely packed. Besides, it was also found that there was not a clear relationship between the tapping density of the powder mixture and the film density.
