A Balance-of-Charges Descriptor for Electron-Delocalized Solvents Enables Calendar-Stable and Thermally Tolerant Silicon-Based Anodes.
Silicon-based anodes provide a practical route to lithium-ion batteries with cell-level energy densities beyond 350 Wh kg- 1, but their calendar life is limited by parasitic reductive reactions at the anode-electrolyte interface. Existing single-parameter electrolyte descriptors, such as lowest unoccupied molecular orb...
