Web31 jul. 2024 · The dispersity of reaction products between Li and solvents are explored by 1H-NMR and first-principles calculations. Lithium ethylene carbonate (LEC), the reduction product of DEC, disperses in the electrolyte, while lithium ethylene dicarbonate (LEDC), the reduction product of EC, cannot disperse in the electrolyte. WebIn this modeling work, we focus on the stability of two main SEI components, lithium carbonate (Li 2 CO 3) and lithium ethylene dicarbonate (LEDC). Both components are electrochemically stable but thermodynamically unstable near … Web4 aug. 2024 · No solvent is used except of LP30 electrolyte for wetting the surface during preparation in glovebox.
