Probing Degradation in Li-ion Cells via EIS

Electrochemical impedance spectroscopy analysis, testing, characterization, or EIS is a powerful technique for investigating, analyzing, probing the internal workings of lithium-ion batteries. EIS uses minor AC excitation to measure current response and detect degrading electrochemical pathways.

Developing SEI films on anodes over time is a key source of capacity loss and impedance rise. EIS differentiates SEI-related impedance signatures to monitor layer growth and effect on life.

Role of Particle Size and Form in Powder Resistivity

Powder resistivity strongly depends on particle physical traits and affects many processing technologies. Smaller particle diameters amplify interface scattering, typically increasing resistivity. Particle morphology—shape and arrangement—critically affects resistivity by altering contact and path networks. Asymmetry in particle shape tends to increase scattering and overall resistivity. Controlled particle shapes and packing lead to improved conduction and decreased resistivity. Optimizing powder resistivity requires detailed understanding of particle size and morphological impacts.
