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 .
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.
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.
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
1. Introduction Lithium-ion batteries (LIBs) attract considerable interest as an energy storage solution in various applications, including e-mobility, stationary, household tools and consumer electronics, thanks to their high energy, power density values and long cycle life .
It’s expected to reach 9,300 gigawatt hours (GWh) by 2030, which translates to a scale-up of about 20 times from 2020 levels. With the rise of electromobility and the consequent increase in EV manufacturing, the market for lithium-ion batteries has seen consistently high growth rates.
