DEIS reveals three distinctive lithium plating processes: no lithium plating (1 and 2 C), lithium nucleation and growth (3 C), and lithium dendrite growth (4 to 6 C). In aged batteries, Li/Li x C 6 (x < 1), organic SEI components, and VC decomposition increase exponentially with increasing charging rate, while inorganic SEI increases slowly
By simulating charge and discharge processes under different levels of wetting, we explore the uneven distribution of lithium plating resulting from inadequate wetting and delve into its underlying mechanisms. Our findings reveal that as the degree of defects increases, the risk of lithium plating at the negative electrode gradually escalates

However, challenges such as dendritic Li deposits, leading to internal short-circuits, and low Coulombic efficiency hinder the widespread adoption of lithium-metal batteries (LMBs). These issues stem from the morphological instability of Li deposition, influenced by dynamic processes at the electrolyte|Li interface. Understanding the interplay
