Skeletal editing of ether-based electrolyte diluents by oxygen-distal fluorination for energy-dense Li metal battery

Nature Communications, Published online: 02 May 2026; doi:10.1038/s41467-026-72634-y Overcoming parasitic reactions between the electrolyte and electrodes is essential for realizing energy-dense lithium metal batteries. Here, the authors develop an oxygen distal fluorinated diluent that promotes a diluent- and anion-rich solvation structure, forming a stable inorganic-rich interphase and stable cycling in pouch cells at 500 Wh kg–1 level.
