Quantitative Analysis of the Nonlinear Frequency Response (also known as Nonlinear Electrochemical Impedance Spectroscopy) for Lithium-Ion Batteries

• Fully nonlinear Newman-type Pseudo-2D models in time-domain and frequency-domain
• Experimental characterization of commercial cells and custom-made cells with production errors
• Development of NFR-based detection of Lithium-Plating for LiB anodes
• Model-based quantification of the potentially hazardous metallic lithium
