Electrochemical impedance spectroscopy (EIS) is used in this procedure to test the impedance in a commercial battery after connecting it two ways. An analysis of the differences in the obtained values ...

Recent battery papers commonly employ interpretation models for which diffusion impedances are in series with interfacial impedance. The models are fundamentally flawed because the diffusion impedance ...

Specifics on ac resistance and why ACIR has become a standard measurement for Li-ions. The 1-kHz test frequency for ACIR and why it's the benchmark frequency. Comparing ACIR test vs. electrochemical ...

One of the more common types of bioelectrical impedance analyzers. Stick-on electrodes are placed onto the hand and foot. The outer electrodes supply the electric current, while the inner pair of ...
