Zinc sulfide energy storage

Can zinc-sulfur batteries revolutionize energy storage?

Abstract In the realm of energy storage, the evolution of zinc-sulfur (Zn-S) batteries has garnered substantial attention, owing to their potential to revolutionize portable and grid-scale power solutions. This comprehensive review covers the triumvirate of anode, cathode, and electrolyte advancements within the Zn-S battery landscape.

Is zinc sulfide good for sodium ion batteries?

Zinc sulfide (ZnS) exhibits promise in sodium-ion batteries (SIBs) because of its low operation voltage and high theoretical specific capacity. However, pristine ZnS is not adequate in realizing rapid and robust sodium storage owing to its low reversibility, poor structure stability, and sluggish kinetics.

Are zinc-sulfur batteries a good choice for grid storage applications?

The affordability of Zn-S batteries makes them particularly promising for grid storage applications. The future outlook for zinc-sulfur batteries appears promising, with potential applications spanning various fields, including energy storage, wearable electronics , and air-compatible structural batteries .

What is a zinc-polysulfide battery?

In the context of zinc-polysulfide batteries (ZPBs), a challenge lies in the reaction between zinc and polysulfide, outlined in section 2.1, resulting in the formation of a ZnS passive layer on the Zn anode. This layer acts as a barrier, hindering further discharge and reversibility .

What is charge storage in zinc anodes in Zn-S batteries?

Charge storage in zinc anodes within Zn-S batteries is fundamentally characterized by a reversible mechanism involving the deposition and stripping of zinc ions, as supported by various references in the literature . During the charging phase, zinc ions undergo reduction and are deposited onto the surface of the zinc anode.

Why is zinc sulfide protective layer important?

The zinc sulfide protective layer well regulates the interfacial electric field and the migration of Zn 2+, thereby significantly promoting the homogenization of zinc ion flux to achieve dendrite-free deposition. In addition, the aqueous zinc ion full cell assembled based on ZnS@3D-Zn anode achieves better output performance in long-term cycles.
