Quality Assurance for batteries
ZEISS eMobility Solutions
A wide range of imaging, analytic and metrology tools are needed to enable battery research and quality control in production of batteries. ZEISS produces light, electron, x-ray-microscopy and computer tomography (CT) systems, as well as coordinate measuring machines to assess and correlate structural, compositional, electrical and dimensional characteristics across the relevant lengths scales. ZEISS thus helps to provide the relevant data to enable battery safety and performance for New Energy Vehicles.
Why is battery quality management in production so important?
Batteries play a key role, especially in new energy vehicles. They are responsible for the range, performance and longevity of the car. However, these factors are not only decisive for the future owner of the electric car, but also for the manufacturer. Safety, durability, performance and cost are crucial to the success of battery technologies.
To produce efficient, reliable batteries that last, it is necessary to use top-quality materials and precise production techniques. Quality criteria range from selecting the best possible materials – including Lithium compounds, anode and cathode materials and separator foils – to control critical steps during the electrode manufacturing process. Understanding the microstructure and possible sources of contamination is key. It is also essential to build cells, modules and trays within very tight tolerances during final assembly. This is the way to ensure the quality management in battery production in the long term.
