Cell/Module/Pack manufacturing 

It takes a lot of power to move an electric car. That's why we need a lot of batteries. But how can we manage many batteries safely and efficiently?

The most basic unit of batteries in electric vehicles is battery cell. Battery cells are made of the elements that make up the battery. After processing battery components such as cathode material, anode material, separator, etc., they can be combined to make a single battery cell.

A battery module refers to a form in which several battery cells are grouped and placed in a frame. This can protect the cell from external impact.

A battery pack is the final unit of a battery placed on an electric vehicle. The battery pack is formed by collecting several modules adding a battery management system (BMS) and a cooling device. Cells come together to become modules, and modules come together to become battery packs. Cells and modules are mixed in series or in parallel to make a battery pack according to a desired voltage, capacity, or power density.

What we need to consider important in this process is whether battery cells, modules, and packs made in this way have the voltage, efficiency, capacity, and stability we want.

When making a battery cell, the stability and energy density of the battery cell are improved depending on how uniformly the battery slurry is coated, which affects the quality of the cell. In Coating process,NETZSCH provides a solution for rheological behavior so that battery slurry can be coated uniformly, and a dispersing solution for low pulse transfer of high viscosity slurry and improvement of coating electrode plate homogeneity.

It also provides Safety & Efficiency solutions for battery screening, such as how efficient the charge/discharge efficiency is, as designed by the cell made.

In addition, we provide a Packaging solution so that the battery packs can maintain thermal stability in packaging process, to be fit on an electric vehicle.
