Lithium-ion has become the battery chemistry of choice for electric and hybrid vehicles, energy storage, consumer electronics, medical equipment and power tools. Thermo Scientific measurement and control systems have an important role in the manufacture of lithium-ion batteries and help to improve their safety, consistency and efficiency and to deliver high quality, reliable products.
Measurement applications for lithium-ion battery
Separator film is one of the key components of a lithium-ion battery and consistent thickness of the film is critical to optimize performance and life of the battery. Thermo Scientific systems for multilayer separator film measurement have been designed to have a wide spectral coverage range, allowing them to measure more material than ever before and provide the highest accuracy and measurement resolution possible.
Uneven coating of the aluminum or copper substrate in a lithium-ion battery results in poor construction and lower efficiency. Thermo Scientific systems for electrode coating weight measurement feature exceptionally high signal with extremely low signal-to-noise-ratio and a unique isotope geometry, resulting in the most accurate coating weight measurement possible and the highest edge resolution.
Accurate thickness measurement of calendered electrodes is essential to avoid excessive calender pressing and retain the porous nature of the electrode. Thermo Scientific™ systems for electrode calendering thickness measurement use the latest confocal technology to precisely measure, control and provide key dimensions of calendered electrode materials and deliver unprecedented resolution, accuracy and repeatability.
