Understanding Lithium Battery Degradation Mechanisms Through EIS Testing

Electrochemical impedance spectroscopy analysis, testing, characterization, or EIS is a powerful technique for investigating, analyzing, probing the internal workings of lithium-ion batteries. Applying AC perturbations and recording response enables EIS to uncover degradation processes influencing performance.

Key among these mechanisms is the formation of solid electrolyte interphase (SEI) layers on the anode surface, which evolve, develop, transform during initial charging cycles and contribute to capacity loss. Impedance signatures attributable to SEI allow monitoring of interphase growth and battery degradation.

Particle Geometry Influence on Powder Electrical Behavior

Electrical resistivity of powders derives from particle geometry and has broad application impact. Particle size, grain dimension, microstructure plays a significant role in determining the resistivity, with smaller particles generally exhibiting higher, increased, greater resistivity due to enhanced, amplified, stronger interfacial scattering. Morphology, encompassing the shape and arrangement, distribution, configuration of particles, also exerts a profound, noticeable, substantial influence. Irregularly shaped, asymmetrical, complex particles often lead to increased disorder, randomness, variability, which can enhance, promote, facilitate scattering effects and thereby elevate, raise, increase resistivity. Ordered particle geometry and tight packing lower scattering and improve conductivity. Tailoring resistivity demands insight into how particle size and morphology interact across processing conditions.
