Summary
Lithium-sulfur batteries require conductive hosts to overcome low conductivity. This review explores nanostructured hosts with functional groups for improved lithium-sulfur battery performance.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Storage
Background:
- Lithium-sulfur (Li-S) batteries offer high energy density potential but face challenges.
- Low electronic conductivity of sulfur and discharge products necessitates conductive host materials.
- Conventional porous carbons struggle to retain polar lithium polysulfides (LiPs).
Purpose of the Study:
- To review recent research on designing sulfur electrodes for Li-S batteries.
- To discuss strategies for improving LiPs retention and electronic conductivity.
- To highlight advancements in nanostructured hosts with functional groups.
Main Methods:
- Review of recent scientific literature on functionalized hosts for Li-S batteries.
- Analysis of strategies including heteroatom doping, organic frameworks, and conductive polymers.
- Discussion of 3D host architectures for enhanced performance.
Main Results:
- Functionalized hosts improve LiPs interactions and cycle life.
- Intrinsic low conductivity of some functionalized hosts limits kinetics and rate capability.
- Nanostructured hosts with conductive functional groups show promise.
Conclusions:
- Designing sulfur electrodes with highly conductive functional groups on nanostructured hosts is crucial.
- Optimized 3D host architectures are key for fast charging and long cycle life.
- Addressing conductivity limitations is vital for realizing high-performance Li-S batteries.

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

48.4K
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.

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

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...

01:09Complexation Equilibria: Factors Influencing Stability of Complexes
739
In complexation reactions, metal cations are the electron pair acceptors, and the ligands are the electron pair donors. The stability of the metal complexes depends primarily on the complexing ability of the central metal ion and the nature of the ligands. Generally, the complexing ability of the metal ion depends on the size and charge of the ion. As the metal ion size increases, the stability of the metal complexes decreases, provided that the valency of the metal ion and the ligands remain...
