Abstract Reactive lithium metal renders it prone to corrosion, which severely limits calendar life and practicality in energy storage. Despite its importance, corrosion-induced degradation remains largely qualitative and lacks a clear mechanistic understanding. Here, we present a quantitatively integrated and experimentally validated framework that correlates lithium corrosion with interphase growth kinetics and interfacial morphological evolution.

1 Introduction Li metal batteries (LMBs) have garnered considerable interest as promising next-generation energy storage systems owing to their exceptionally high theoretical specific capacity (3860 mAh g−1) and highly negative standard reduction potential (−3.04 V vs SHE).[1-3] Despite these attractive attributes, the practical deployment of LMBs is significantly impeded by persistent issues such as dendrite growth, unstable solid electrolyte interphase (SEI) layers, and low Coulombic...
