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 .
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.
In particular, the lithium-ion battery, with its high energy density, has established itself as the leading electricity storage technology in recent years. Without the powerful lithium-ion batteries, there would be no electric cars (EV's), smartphones, laptops.
A tool for quality-oriented production planning in assembly of battery modules was developed by , defining critical product and process characteristics and deriving appropriate quality assurance systems using a measurement equipment catalogue.
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].
