Formation of Complex Ions03:45

Formation of Complex Ions

23.5K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Ion Exchange01:17

Ion Exchange

565
Ion exchange chromatography separates charged molecules from a solution by reversibly exchanging them with mobile, or 'active', ions associated with the oppositely charged stationary phase. This method can be used to separate ions, soften and deionize water, and purify solutions. The polymers comprising the ion-exchange column are high-molecular-weight and chemically stable polymers, crosslinked to be porous and essentially insoluble. They are also functionalized with either acidic or...

Ionic Bonding and Electron Transfer

41.3K
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.

Trends in Lattice Energy: Ion Size and Charge

23.8K
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:

Molecular and Ionic Solids02:54

Molecular and Ionic Solids

17.0K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Solid-State Chemistry

Background:

  • Lithium argyrodite sulfide electrolytes are promising for all-solid-state lithium metal batteries (ASSLMBs) due to high ionic conductivity and ductility.
  • Li6PS5I exhibits good stability with lithium metal but suffers from low ionic conductivity (≈10-6 S cm-1) caused by the absence of S2-/I- disorder, hindering Li+ ion migration.
  • Overcoming these limitations is crucial for developing high-performance and stable ASSLMBs.

Purpose of the Study:

  • To design argyrodite particles with an iodine-gradient-disordered interphase to enhance Li+ ion conductivity and battery stability.
  • To investigate the mechanisms behind improved ionic conduction and interfacial stability.
  • To demonstrate the potential of this novel interphase design for ultrastable ASSLMBs.

Main Methods:

  • Design and synthesis of argyrodite particles with a specific iodine-gradient-disordered interphase.
  • Density functional theory (DFT) calculations to analyze Li+ ion migration barriers and intercage jumps.
  • 7Li spin-lattice relaxation NMR experiments to confirm activated Li+ conduction.
  • Electrostatic potential profiling to assess the electron-shielding capability of the interphase.
  • Electrochemical characterizations including ionic conductivity, electron conductivity, critical current density, cycling stability, and rate performance tests.

Main Results:

  • The designed iodine-gradient-disordered interphase successfully opened up Li+ ion intercage jumps and reduced migration barriers, as evidenced by DFT and NMR.
  • The interphase demonstrated effective electron shielding, preventing parasitic reactions at the Li metal interface.
  • Achieved high ionic conductivity (5.7 mS cm-1), low electron conductivity (1.5×10-8 S cm-1), improved critical current density (1.65 mA cm-2), and excellent stability with Li metal (>1,500 h).
  • Demonstrated prominent cycling and rate performance in ASSLMBs.

Conclusions:

  • The novel interphase design effectively enhances ionic conductivity by facilitating Li+ ion intercage migration.
  • The disordered interphase provides robust protection against electron leakage, ensuring high Li metal compatibility and battery stability.
  • This study offers valuable insights into designing advanced interphases for high-performance ASSLMBs, balancing ionic conductivity and interfacial stability.
