Solid electrolyte interphaseInterfacial processes of lithium (Li) deposition and solid electrolyte interphase (SEI) formation are key determinants of the safety and performance in high-energy Li metal batteries. With the vigorous growth of effective strategies for stabilizing the interfaces, high-...
Li+transport within a solid electrolyte interphase (SEI) in lithium ion batteries has challenged molecular dynamics (MD) studies due to limited compositional control of that layer. In recent years, experiments andab initiosimulations have identified dilithium ethylene dicarbonate (Li2EDC) as the ...

Reactions occurring on the surface of a Sn/carbon/binder composite electrode during the lithiation process are presented for illustration. The new method provides insight into the dynamics of electrode reactions, shape changes of particles, spatial distribution of solid electrolyte interphase reactions, ...
Ab initio molecular dynamics simulations of the initial stages of solid-electrolyte interphase formation on lithium ion battery graphitic anodes. The decomposition of ethylene carbonate (EC) during the initial growth of solid–electrolyte interphase (SEI) films at the solvent–graphitic anode interfa.....

Li metal batteries (LMB) have regained broad interest in the energy storage system field, thanks in part to the use of molecular dynamics (MD) simulation in the rational design of LMBs. The progress of MD simulations in LMBs with respect to the electrolyte, solid electrolyte interphase, and ...
Nondestructive Depth Profiling of the Solid Electrolyte Interphase on LiFePO4 and Graphite Electrodes This study describes a method for non-destructive depth profiling of the electrode/electrolyte interphase in lithium-ion batteries. Photoelectron spectroscopy (PES) measurements using four different excitation ...
Among components of a battery, electrolytes play a central role in the performance and safety of lithium ion batteries1,2,4–10. They allow for lithium ions to conduct between cathode and anode of batter- ies and contribute to form a solid electrolyte interphase (SEI) which is a key ...
