Challenges in Industrial Battery Cell Manufacturing The basis for reducing scrap and, thus, lowering costs is mastering the process of cell production. The process of electrode production, including mixing, coating and calendering, belongs to the discipline of process engineering.
Key challenges include the complexity of both the product and process, the novelty of battery production in regions like Europe and the U.S., the scale and automation level of facilities, the availability of skilled workers. Additionally, cultural, and linguistic barriers can further complicate operations.
For battery manufacturing, the core issues are how to reduce manufacturing costs, increase production efficiency, and improve the good rate of cells . The traditional production methods based on manual experience obviously can no longer meet the requirements of Industry 4.0.
The new manufacturing technologies such as high-efficiency mixing, solvent-free deposition, and fast formation could be the key to achieve this target. Besides the upgrading of battery materials, the potential of increasing the energy density from the manufacturing end starts to make an impact.
Employees need to be well-versed not only in the operational aspects of production equipment but also in the underlying principles of battery technology. This dual approach ensures that workers can effectively troubleshoot and optimize processes, leading to higher efficiency and quality in production.
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.
