The production of lithium-ion batteries is a complex process that requires attention to detail at every stage to ensure the final product meets high performance, reliability, and safety standards. Therefore, testing plays a critical role in validating the quality of materials, components, and the final battery assembly.
From raw materials inspection to end-of-line testing, various testing methods and protocols are employed to assess and guarantee the integrity and functionality of lithium-ion batteries. Once the raw materials have been tested and approved, they are processed and assembled into battery components, including electrodes, separators, and electrolytes.
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 upcoming restrictions on internal combustion engines for automotive applications are also driving research and development into more effective ways of storing energy and limiting environmental pollution, and lithium-ion battery technologies are at the forefront of these efforts.
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
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.
