💡 Novelty & Significance:
The novelty lies in a strain-sensing current collector integrating Constantan sensors into copper via transfer printing and electroplating, preserving cell function. It enables operando probing of graphite lithiation, rate-dependent and low-temperature degradation strains, and decouples reversible from irreversible strain. This offers a practical strategy for studying electrochemical-mechanical coupling in operating lithium-ion batteries without disrupting cell structure.
