The rise in battery production faces challenges from manufacturing complexity and sensitivity, causing safety and reliability issues. This Perspective discusses the challenges and opportunities for high-quality battery production at scale.
In summary, the quality of the production of a lithium-ion battery cell is ensured by monitoring numerous parameters along the process chain. In series production, the approach is to measure only as many parameters as necessary to ensure the required product quality. The systematic application of quality management methods enables this approach.
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%.
However, the manufacturing defects, caused by production flaws and raw material impurities can accelerate battery degradation. In extreme cases, these defects may result in severe safety incidents, such as thermal runaway.
