Inorganic interfaces can enhance aqueous zinc batteries by suppressing zinc dendrites and hydrogen evolution. This review explores materials and mechanisms for stable zinc anodes, enabling practical energy storage solutions.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Storage
Background:
- Aqueous zinc metal batteries (AZMBs) offer safety and cost benefits but face challenges.
- Zinc dendrite growth and hydrogen evolution reaction (HER) hinder industrial application.
Purpose of the Study:
- To review the impact of inorganic interfaces on zinc anodes in AZMBs.
- To highlight protection mechanisms against dendrites and HER.
- To provide perspectives on designing advanced interfaces for stable AZMBs.
Main Methods:
- Literature review focusing on inorganic materials (metal oxides, compounds, salts).
- Analysis of protection mechanisms for zinc metal anodes.
- Discussion of interface engineering for Zn2+ plating/stripping.
Main Results:
- Inorganic interfaces significantly influence Zn2+ plating/stripping and cell performance.
- Various inorganic materials demonstrate dendrite and HER inhibition capabilities.
- Understanding these interfaces is crucial for improving AZMB stability.
Conclusions:
- Rational design of inorganic interfaces is key to achieving reversible Zn2+ plating/stripping.
- Advanced interfaces can overcome current limitations in AZMBs.
- This research paves the way for practical AZMB implementation in energy storage.
