Electrochemical Impedance to Study Battery Deterioration

EIS characterization probes underlying mechanisms inside lithium batteries enabling degradation analysis. Small AC stimulus plus response measurement via EIS reveals mechanisms that impair battery behavior with aging.

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. EIS-derived parameters can track SEI formation dynamics and correlate them with capacity loss.

Effect of Particle Microstructure on Powder Resistivity

Powder electrical response is dictated by particle-level properties and matters in varied processes. Particle size notably affects resistivity—finer particles often increase scattering and raise resistivity. Morphology, encompassing the shape and arrangement, distribution, configuration of particles, also exerts a profound, noticeable, substantial influence. Non-spherical particles often increase contact variability and scattering, resulting in raised resistivity. Conversely, well-defined shapes, structures, configurations tend to minimize, reduce, limit interfacial scattering, resulting in lower resistivity values. Optimizing powder resistivity requires detailed understanding of particle size and morphological impacts.
