EA-BIM 20005

Accurate Electrochemical Impedance Measurements Within Seconds
A new solution from Tektronix provides the fastest EIS measurements in the industry for assessment of the quality and health of lithium-ion battery cells. Quality control of lithium-ion battery (Li-ion) cells ensures that cells that are shipped or built into battery modules and battery packs are free of defects and have a high state-of-health (SoH). Electrochemical impedance spectroscopy (EIS) provides substantial insight into the quality of Li-ion battery cells. However, accurately testing high volumes of battery cells can be a time-consuming bottleneck.

Tektronix offers an innovative method that speeds up EIS measurements by a factor of over 100, so you can accurately test more batteries and test them faster.
