The anode and cathode materials are mixed just prior to being delivered to the coating machine. This mixing process takes time to ensure the homogeneity of the slurry. Cathode: active material (eg NMC622), polymer binder (e.g. PVdF), solvent (e.g. NMP) and conductive additives (e.g. carbon) are batch mixed.

The production of lithium-ion battery cells primarily involves three main stages: electrode manufacturing, cell assembly, and cell finishing. Each stage comprises specific sub-processes to ensure the quality and functionality of the final product.
Cell assembly can be roughly divided into three process routes for the three cell types (cylindrical, prismatic, pouch). The only thing the three routes have in common is the start with the cut-to-size electrode coils and the sealed cell as the end product, since the process guidance and the required equipment technology differ greatly.
A lithium battery pilot line refers to a production line or facility used for the initial testing, development, and small-scale production of new battery technologies or battery-related products. It serves as an intermediate step between laboratory-scale research and full-scale commercial production. The primary purpose of a battery pilot line is to validate and refine

The first stage, electrode manufacturing, is crucial in determining the performance of the battery.
In the formation process (which has already taken place for the pouch), the cell is charged for the first time, which virtually activates the battery cell. The charging and discharging of the battery cell must be carried out in a very controlled manner so that the SEI (Solid Electrolyte Interface) forms in a thin and homogeneous layer on the anode.
The first stage in battery manufacturing is the fabrication of positive and negative electrodes. The main processes involved are: mixing, coating, calendering, slitting, electrode making (including die cutting and tab welding). The equipment used in this stage are: mixer, coating machine, roller press, slitting machine, electrode making machine.
