The physicochemical properties of electrolytes profoundly impact the energy density, rate performance, and manufacturability rechargeable lithium batteries. Localized high-concentration (LHCEs), a novel electrolyte class, have attracted considerable interest, yet diluents on their remains unclear, as most reports involve only few samples. Here we prepared 345 samples using 21 systematically investigated effect diluent type content miscibility, viscosity, ion conductivity LHCEs. We found that LHCEs are mainly affected by diluents' density regardless type. Notably, ionic exhibits two typical variance trends, "volcano" "descending," both correlating strongly with viscosity rather than dielectric constant, parameter commonly employed in design. This anomaly can be explained "plum pudding" solvation model, providing essential insights for developing lightweight, highly fluid, conductive

Lithium metal batteries (LMBs) have been recognized as high-energy storage alternatives; however, problematic surface reactions due to dendritic Li growth are major obstacles their widespread utilization. Herein, a 3-mercapto-1-propanesulfonic acid sodium salt (MPS) with asymmetrically functionalized thiol and sulfonate groups polarizable interface-restructuring molecules is proposed achieve rapid longer-operating LMBs. Under harsh condition of 5 mA cm
