Are sulfur cathodes a viable energy storage solution?

Batteries based on sulfur cathodes offer a promising energy storage solution due to their potential for high performance, cost-effectiveness, and sustainability. However, commercial viability is challenged by issues such as polysulfide migration, volume changes, uneven phase nucleation, limited ion transport, and sluggish sulfur redox kinetics.

What are the electrochemical processes of metal sulfur batteries?

The charge and discharge processes involve multistep reactions, that is, the transformation of metal S and polysulfides. But, different metal ions lead to different electrochemical processes of sulfur in various metal sulfur batteries. The electrochemical processes of various metal sulfur batteries are summarized and discussed in Fig. 2.

How are sulfur-based batteries characterized?

Several in situ and operando characterization techniques have been employed to study the components and processes of sulfur-based batteries. The morphological evolution of sulfur, lithium sulfides, solid electrolyte interphase (SEI) layers, and lithium during cycling has been tracked using (S)TEM, SEM, AFM, OM, XTM, and NI.

Are metal sulfur batteries a good candidate for next-generation rechargeable batteries?

Metal sulfur batteries have become a promising candidate for next-generation rechargeable batteries because of their high theoretical energy density and low cost. However, the issues of sulfur cathodes and metal anodes limited their advantages in electrochemical energy storage.
