Figure 4. Electrolyte interaction with V₂AB₄ monolayers: (A) schematic representation of the interactions between representative electrolyte species and the V₂AB₄ surfaces; (B) corresponding adsorption energies of carbonate solvents and Na⁺/K⁺ salts on the V₂AB₄ substrates; (C) Top and side views of DEC, EC, and FEC adsorbed on V₂MoS₄, V₂MoSe₄, V₂WS₄, and V₂WSe₄ surfaces. DEC: Diethyl carbonate; EC: ethylene carbonate; FEC: fluoroethylene carbonate; NaFSI: sodium bis(fluorosulfonyl)imide; NaPF6: sodium hexafluorophosphate; KFSI: potassium bis(fluorosulfonyl)imide; KPF₆: potassium hexafluorophosphate.
