Formation of Complex Ions03:45

Formation of Complex Ions

25.6K
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...

Ionic Crystal Structures02:42

Ionic Crystal Structures

16.7K
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Ion Exchange01:17

Ion Exchange

1.1K
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 Transfer02:48

Ionic Bonding and Electron Transfer

48.5K
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.

Common Ion Effect03:24

Common Ion Effect

45.5K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

Ionic Strength: Overview01:12

Ionic Strength: Overview

2.7K
The ionic strength of a solution is a quantitative way of expressing the total electrolyte concentration of a solution. This concept was first introduced in 1921 by two American physical chemists, Gilbert N. Lewis and Merle Randall, while describing the activity coefficient of strong electrolytes. During the calculation of ionic strength (I or μ), all the cations and anions are considered. However, the concentration (c) of an ion with a greater charge number (z) has a greater contribution...

Summary

A new study shows that symmetrical fluorinated sulfonylimide anions in ionic liquid electrolytes create a robust solid electrolyte interphase (SEI) on silicon anodes. This stable SEI significantly improves the lifespan and performance of lithium-ion batteries.

Area of Science:

  • Materials Science
  • Electrochemistry
  • Battery Technology

Background:

  • A stable solid electrolyte interphase (SEI) is crucial for the longevity of silicon anodes in lithium-ion batteries (LIBs).
  • Conventional carbonate electrolytes yield unstable SEIs, limiting the practical use of Si anodes.
  • Fluorinated sulfonylimide (FSI-/TFSI-) based ionic liquid (IL) electrolytes offer a promising alternative for SEI formation and enhanced capacity retention.

Purpose of the Study:

  • To investigate the role of symmetric and asymmetric anions in directing SEI formation and evolution in IL-based electrolytes.
  • To elucidate the mechanistic interplay between anion decomposition pathways and interfacial chemistry.
  • To understand how IL electrolytes impact SEI properties and silicon anode performance.

Main Methods:

  • Investigated SEI chemistry and morphology using various imidazolium-based ILs with symmetric and asymmetric anions.
  • Analyzed SEI composition (e.g., LiF, LiOH, Li2SO4) and structure using surface analysis techniques.
  • Correlated electrochemical performance (capacity retention, cycling stability) with SEI characteristics.

Main Results:

  • Symmetrical bis(fluorinated sulfonyl)imide anions synergize with imidazolium cations to form an inorganic-rich inner SEI (LiF/LiOH) and a Li2SO4/polymeric outer layer.
  • This conformal SEI coating on 3D Si anodes enhances mechanical integrity and flexibility.
  • Achieved a reversible capacity of 2489 mAh/g at 1C over 250 cycles, demonstrating improved battery performance.

Conclusions:

  • The synergistic interaction of symmetrical fluorinated sulfonylimide anions and imidazolium cations is key to forming a robust, multi-layered SEI.
  • The resulting SEI effectively suppresses Si anode pulverization and enhances cycle life.
  • Findings provide critical insights for designing advanced ionic liquid electrolytes for high-performance LIBs.
