A wide range of imaging, analytic and metrology tools are needed to enable battery research and quality control of batteries. ZEISS produces light, electron, x-ray-microscopy and computer tomography (CT) systems, as well as coordinate measurement 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.
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’s also essential to build cells, modules and trays within very tight tolerances during final assembly.
