Summary
Two-dimensional materials act as ionic sieves to suppress the shuttle effect, improving the performance of next-generation batteries like lithium-sulfur and organic batteries.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Storage
Background:
- Commercial lithium-ion batteries (LIBs) face resource limitations and high demand.
- Alternative battery chemistries like Li-S, organic, and flow batteries are promising but suffer from active material dissolution and shuttle effects, leading to capacity loss and poor cycle life.
Purpose of the Study:
- To review the advances and perspectives of using two-dimensional (2D) materials as ionic sieves.
- To address the shuttle effect challenge in advanced battery systems.
Main Methods:
- Review of existing literature on 2D materials in battery applications.
- Analysis of the role of 2D materials in suppressing active material dissolution and shuttle effects.
Main Results:
- 2D materials, with their unique structures and properties, can effectively inhibit the shuttle effect.
- This suppression of shuttle effect by 2D materials leads to improved capacity retention and cycling stability.
Conclusions:
- 2D materials offer a promising strategy to overcome key challenges in next-generation batteries.
- Further research into 2D materials as ionic sieves can pave the way for high-performance energy storage systems.

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.

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...

Overview
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.
Opposing Charges Hold Ions Together in Ionic Compounds
Ionic bonds are reversible electrostatic interactions between ions...

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...
