EV battery manufacturing quality starts with the raw materials. Separator film/coating inspections can help catch defects in the material before further processing. Make sure you inspect every battery cell for surface damage at full in-line production speed and not impact productivity.
Due to the dominance of material costs and the length of the process chain, battery cell and pack costs are very sensitive to production errors. For example, a process chain with 25 steps, each having a yield of 99.5%, would result in an overall yield of only 88.2%.
Developments in different battery chemistries and cell formats play a vital role in the final performance of the batteries found in the market. However, battery manufacturing process steps and their product quality are also important parameters affecting the final products’ operational lifetime and durability.
Battery manufacturers must not only deliver consistent overall quality, but they must also deliver it throughout the manufacturing process. Quality needs to be monitored at every stage from raw materials through to cell assembly to maintain production efficiency and minimize waste.
The choice of materials, components and cells has a major impact on pack design. At the same time, pack requirements also constrain the properties of the materials and cells. This increases the complexity of battery development for EVs. Fig. 1: Components of LIB packs and a mass content breakdown.
Ensuring operator safety during the production of EV batteries is critical because the cells and modules that make up the battery are electrically charged, with DC voltage levels ranging from a few hundred up to a thousand. Risk assessment needs to be carried out.
