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...

Batteries and Fuel Cells

30.7K
A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Ionic Crystal Structures

16.8K
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...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Solid-State Chemistry

Background:

  • Anion substitution in crystalline solids is challenging, limiting the development of polyanionic compounds.
  • Polyanionic compounds are crucial for high-voltage applications in energy storage.

Purpose of the Study:

  • To investigate the formation and properties of anion-regulated polyanionic compounds.
  • To explore Fe-based intercalation compounds with tunable anionic frameworks for sodium-ion batteries.

Main Methods:

  • Synthesis of Fe-based polyanionic compounds with varying Mo/S ratios: Fe2[(MoO4)1-x(SO4)x]3.
  • Characterization of crystal structures and phase identification (monoclinic and rhombohedral).
  • Electrochemical evaluation of Na+ storage capability, operating voltage, and low-temperature performance.

Main Results:

  • Identified two solid-solution regions: monoclinic (0 ≤ x ≤ 0.3) and rhombohedral (0.8 ≤ x ≤ 1).
  • Sulfur substitution increased operating voltage by 0.22 V and enhanced Na+ intercalation kinetics.
  • Optimized monoclinic phase (FMSO) showed superior Na storage (1.99 Na+ per formula) and excellent low-temperature power (-40 °C).

Conclusions:

  • Anion-regulated polyanionic compounds can be successfully formed by substituting S for Mo.
  • Sulfur substitution offers a viable strategy to enhance voltage and kinetics in Fe-based cathodes.
  • This work broadens the scope of anionic solid-solution design for high-power, cost-effective sodium-ion batteries.
