  "abstract": "Coulombic efficiency (CE) is a key metric governing the cyclability of lithium metal anodes, motivating efforts to identify physicochemical descriptors that correlate with CE. Diverse descriptors spanning electrolyte thermodynamics and interphase properties have been proposed, but their interrelationships and underlying physical origins remain unclear. Here we show that, when evaluated across a consistent electrolyte set, these descriptors exhibit a common hockey-stick relationship with CE that can be unified through the mesoscale connectivity of lithium deposits. A percolation-like transition from isolated deposits to interconnected networks sharply suppresses inactive Li0 formation during stripping, which underlies the common CE transition across descriptors. Tuning plating current density reproduces this transition within individual electrolytes, demonstrating that connectivity is not uniquely determined by electrolyte chemistry. These findings establish lithium connectivity as a common mechanistic basis for diverse CE correlations and provide a framework for interpreting these correlations across distinct capacity-loss regimes.",
