Organic solid-electrolyte interface layers for Zn metal anodes

Area of Science:

• Materials Science
• Electrochemistry
• Energy Storage

Background:

• Zinc ion batteries (ZIBs) are attractive for renewable energy due to cost, safety, and sustainability.
• Zn metal anodes suffer from dendrite growth, hydrogen evolution reaction (HER), and corrosion, limiting ZIB practicality.

Purpose of the Study:

• To review recent advancements in organic artificial solid electrolyte interface (SEI) layers for ZIB anodes.
• To highlight fabrication methods, electrochemical performance, and degradation suppression mechanisms of these SEI layers.

Main Methods:

• Summarizing recent research on organic artificial SEI layers for ZIB anodes.
• Analyzing fabrication techniques and electrochemical testing of SEI-modified Zn anodes.

Main Results:

• Organic artificial SEI layers promote uniform Zn plating/stripping.
