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 .
Having powerful and robust solutions for analysis in battery and energy materials is of the utmost importance, especially in light of the increase in the production of electric vehicles (EVs), the continued high demand for consumer electronics such as smartphones, and the forecasted growth in the use of electronic medical devices.
A powerful tool is presented to directly measure battery self-discharge. Precise self-discharge currents are measured with a high resolution of 0.25 µA. Experimental investigation of the method is done based on temperature and SoC. Arrhenius analysis of self-discharge provides chemical insights to the LiB cells.
As the landscape of alternate energy methods for high technology and consumer goods such as, electric vehicles (EV) and bikes, smartphones and laptop advances, R&D is increasing to continually develop new types of batteries. In addition, QA/QC methods for lithium ion battery producers are also becoming more stringent.
Innovative analytical solutions for testing every part of the battery, including the anode, cathode, binder, separator, and electrolytes, are demonstrated.
