The production of batteries involves depositing a slurry containing active materials, conductive materials and solvents and polymer binders onto a copper film or aluminum film. This is followed by drying, calendering and resizing of the electrodes.<\/p>\n

Slurry is a very complex suspension system containing many solid particles of different chemicals, sizes and shapes in a high viscosity medium. Thorough mixing of the slurry is essential for homogeneity. The rheological properties of a slurry affect important properties such as slurry stability, ease of mixing, and coating performance, as well as the finished electrode. The composition and applied processing conditions can affect the rheology of the slurry.<\/p>\n

Density and viscosity quantify flow properties and characterize the degree of structure within a sample and the extent to which solid- or liquid-like behavior dominates. The viscosity of the slurry is particularly important in the electrode manufacturing process and plays an important role in battery manufacturing processes such as coating. The viscosity of the polymer binder solution affects coating performance. It affects the ease with which the powder is dispersed within it, the force required for mixing and the speed of application of a uniform coating.<\/p>\n\n<\/div>
