Quality management for complex process chains Due to the complexity of the production chain for lithium- ion battery production, classical tools of quality management in production, such as statistical process control (SPC), process capability indices and design of experiments (DoE) soon reach their limits of applicability .
The manufacturing data of lithium-ion batteries comprises the process parameters for each manufacturing step, the detection data collected at various stages of production, and the performance parameters of the battery [25, 26].
4.1. Method for quality man agement in battery production quality management during production. This procedure can be format and process structure. Hence, by detecting deviations in control and feedback are facilitated. properties. Among the external requirements are quality performance or lifetime of th e battery cells . Internal
A detailed product model for lithium-ion cells was presented by . Most common formats cover cylindrical cells, prismatic hard case cells and pouch cells. The production of lithium-ion cells has a big impact on cost and quality of the batteries [3,17].
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.
It has been shown that current quality management tools easily face their limits when applied to the production chain of lithium-ion cells due to its complexity and the need for real time processing of collected data.
