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.

Batteries Cell-to-pack – Potentials of Compact Battery Design along the Lifecycle lar aging process [4]. Once the use of the battery system in the vehicle is no longer ef˜cient due to its aging, the entire pack can be used for second-life operation, for example as a buffer storage system. The process of remanufacturing, which is a complex one in the cell-to-pack concept, can be
The production of the lithium-ion battery cell consists of three main process steps: electrode manufacturing, cell assembly and cell finishing. Electrode production and cell finishing are largely independent of the cell type, while within cell assembly a distinction must be made between pouch cells, cylindrical cells and prismatic cells.
However, the environmental impact of battery production begins to change when we consider the manufacturing process of the battery in the latter type. You might also like: Why Electric Cars Are Better for the Environment.

It is composed of 16 modules with 432 cells of the type 18650 and a NCA chemistry, resulting in a total of 6912 cells in each pack. (42) Furthermore, the cells inside the modules are packed in groups which are wired in series to each other, creating a battery inside the battery. The same goes for the modules which also are connected in series.
The design solutions are assessed from an assembly, disassembly and modularity point of view to establish what solutions are of interest. Based on the evaluation, an “ideal” battery is developed with focus on the hardware, hence the housing, attachment of modules and wires, thermal system and battery management box.
The battery pack assembly is the process of assembling the positive electrode, negative electrode, and diaphragm into a complete battery. This involves placing the electrodes in a cell casing, adding the electrolyte, and sealing the cell.
The BMS and power relays can be found inside the pack whereas the DC-DC converter, HV controller and other HV units are mounted in other parts of the vehicle. Furthermore, the pack consist of ten modules, divided in two rows and two levels with the lower modules containing 30 cells and the upper modules 24.
Battery ingredients (cathode, anode, separator, electrolyte) are placed in the former and electrolytes are injected and gas is stored in the latter. The ingredients are piled up in the electrode pocket using “lamination and stacking” method and electrolyte is injected into the air pocket to reach even pores in the electrode pocket.
