Assess learners' ability to analyze failure mechanisms and degradation pathways in lithium‑ion cells subjected to high‑rate (high C‑rate) cycling. Scope includes electrochemical and mechanical processes (SEI evolution, lithium plating, electrode cracking/particle isolation, electrolyte decomposition, thermal effects), interpretation of diagnostics (cycling curves, coulombic efficiency, EIS, post‑mortem microscopy/XRD), modeling approaches, and mitigation strategies; tasks include interpreting data, distinguishing mechanisms, and proposing experiments or design/operational remedies.
