Batteries and Fuel Cells

Batteries and Fuel Cells

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...

Formation of Complex Ions

Formation of Complex Ions

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...

Types of Reversible Electrodes

Types of Reversible Electrodes

For electrode reversibility to be maintained, all the reactants and products involved in the half-reaction must be present at the electrode. There are several types of reversible electrodes (half-cells).In metal-metal-ion electrodes, a metal balances electrochemically with a solution of its own ions. Examples are Cu2+|Cu and Zn2+|Zn. Metals that react with the solvent, like group 1 and most group 2 metals, which react with water, and zinc, which reacts with aqueous acidic solutions, cannot be...

Ionic Strength: Effects on Chemical Equilibria

Ionic Strength: Effects on Chemical Equilibria

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 cation—the calcium...

Electrochemical Systems

Electrochemical Systems

Electrochemical systems provide a fascinating insight into the dynamic interplay of charged species within various phases. One notable example is the interaction between a membrane permeable to K⁺ ions but not to Cl⁻ ions, separating an aqueous KCl solution from pure water. As K⁺ ions diffuse through the membrane, they generate net charges on each phase, leading to a potential difference between them.Similarly, when a piece of Zn is immersed in an aqueous ZnSO₄ solution, the Zn metal, composed...

Ionic Bonding and Electron Transfer

Ionic Bonding and Electron Transfer

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.

Background:

Conversion-type transition-metal sulfides are promising anodes for sodium-ion batteries (SIBs) due to high capacity and conductivity.
However, poor reversibility and stability caused by volume expansion limit their practical use.

Purpose of the Study:

To develop intrinsically stable sulfide anodes for SIBs using high-entropy design.
To overcome the limitations of conventional nanostructuring and carbon encapsulation methods.

Main Methods:

Constructed a single-phase high-entropy sulfide (HES) anode.
Investigated the effect of the multication framework on reaction reversibility and structural stability.

Main Results:

The HES anode demonstrated high initial Coulombic efficiency (94.8%) and excellent rate capability (486.1 mAh g⁻¹ at 50 A g⁻¹).
Achieved remarkable cycling stability, retaining 547 mAh g⁻¹ after 2000 cycles at 5 A g⁻¹.
The HES structure homogenized local environments, reduced stress, and improved charge transfer and ion diffusion.

Conclusions:

High-entropy design intrinsically stabilizes sulfide conversion anodes, enhancing reversibility and durability.
The HES platform shows significant potential for fast-charging, high-stability anodes in next-generation SIBs.
