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...

Background:

Lithium-oxygen batteries (LOBs) offer high energy density but suffer from poor efficiency and lifespan due to non-conductive Li₂O₂.
Large overpotentials during charging and solvent breakdown hinder practical LOB implementation.
Improving oxygen reduction (ORR) and evolution (OER) kinetics is crucial for LOB advancement.

Purpose of the Study:

To review the role of single-atom catalysts (SACs) in enhancing lithium-oxygen battery performance.
To examine SAC structural design, catalytic mechanisms, and their impact on battery efficiency.
To discuss current challenges and future prospects for SACs in LOB technology.

Main Methods:

Literature review focusing on SACs for LOBs.
Analysis of theoretical approaches, including density functional theory (DFT), to understand SAC mechanisms.
Investigation of SAC structural, electronic, and adsorption properties.

Main Results:

SACs demonstrate exceptional catalytic activity for ORR/OER due to maximized surface exposure.
Theoretical analysis reveals insights into active site configuration, charge, and electronic structure.
SACs effectively reduce charge polarization and mitigate solvent degradation, improving battery lifespan.

Conclusions:

SACs are vital for advancing lithium-oxygen battery technology by enhancing reaction kinetics and efficiency.
Further research into SAC synthesis, characterization, and integration is needed for practical LOB applications.
Optimizing SAC design and understanding reaction mechanisms are key to overcoming current limitations.
