Ionic Bonding and Electron Transfer02:48

Ionic Bonding and Electron Transfer

41.7K
Ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds composed of ions are called ionic compounds (or salts), and their constituent ions are held together by ionic bonds: electrostatic forces of attraction between oppositely charged cations and anions.

Solubility of Ionic Compounds02:55

Solubility of Ionic Compounds

63.3K
Solubility is the measure of the maximum amount of solute that can be dissolved in a given quantity of solvent at a given temperature and pressure. Solubility is usually measured in molarity (M) or moles per liter (mol/L). A compound is termed soluble if it dissolves in water.

Trends in Lattice Energy: Ion Size and Charge

24.0K
An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a measure of the strength of this attraction. The lattice energy (ΔHlattice) of an ionic compound is defined as the energy required to separate one mole of the solid into its component gaseous ions. For the ionic solid sodium chloride, the lattice energy is the enthalpy change of the process:

Ionic Strength: Effects on Chemical Equilibria01:19

Ionic Strength: Effects on Chemical Equilibria

1.5K
The addition of an inert ionic compound increases the solubility of a sparingly soluble salt. For example, adding potassium nitrate to a saturated solution of calcium sulfate significantly enhances the solubility of calcium sulfate. Le Châtelier's principle cannot predict this shift in the equilibrium. Instead, this could be explained in terms of changes in the effective concentration of the ions in solution in the presence of added inert salt.
In this solution, the primary...

Intermolecular Forces03:13

Intermolecular Forces

58.6K
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Area of Science:

  • Electrochemistry
  • Materials Science
  • Computational Chemistry

Background:

  • Iodide-based redox mediators offer high round-trip efficiency in lithium-oxygen (Li-O2) batteries.
  • Solvation of iodide ions (I-) is critical for efficient redox mediation.

Purpose of the Study:

  • To investigate the influence of electrolyte composition on iodide (I-) solvation in Li-O2 batteries.
  • To understand how glyme chain length and water content affect ion interactions.

Main Methods:

  • Molecular dynamics simulations were employed.
  • Combinatorial exploration of iodide (I-), water (H2O), and lithium-ion (Li+) concentrations in glymes (G1-G4).

Main Results:

  • Shorter glymes promote closer packing of the iodide (I-) redox mediator.
  • Increased iodide (I-) concentration reduces lithium-ion (Li+) solvation, particularly in G2.
  • Water addition enhances interactions between iodide (I-) and lithium-ion (Li+), with greater effect in shorter glymes.

Conclusions:

  • Electrolyte composition, specifically glyme chain length and water content, significantly modulates ion solvation and interactions.
  • Optimizing electrolyte formulation is key to enhancing the performance of iodide-mediated Li-O2 batteries.
