Electrochemical Impedance Spectroscopy (EIS) shows great promise for analyzing degradation mechanisms and evaluating the performance of lithium-ion battery cells. However, its practical implementation still faces several challenges. These include the complexity and error risks associated with traditional station-based testing processes, difficulties in ensuring stability and reproducibility in low-impedance measurements, and the high cost of dedicated EIS equipment, which hinders its scalability.

Chroma has introduced a battery reliability test system integrated with EIS functionality, enabling
automated switching between DC charge/discharge and AC impedance measurements.

Download this whitepaper to learn how this innovation eliminates the need for separate EIS testing stations: battery connections are made once with no need for repeated handling or rewiring, which significantly reduces labor demands and operational errors.
