Summary
Stabilizing the solid electrolyte interphase (SEI) on sodium metal anodes using artificial layers is key for safer, longer-lasting sodium metal batteries (SMBs). This review explores materials and methods for enhancing SEI stability and performance.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Storage
Background:
- The solid electrolyte interphase (SEI) on sodium (Na) metal anodes is crucial for Na metal battery (SMB) performance.
- An unstable SEI and Na dendrite growth lead to low coulombic efficiency and safety concerns in SMBs.
Purpose of the Study:
- To review recent advances in artificial interphase engineering for stabilizing Na metal anodes.
- To highlight the significance of interface engineering for improving SMBs.
Main Methods:
- Focus on artificial interphase engineering using inorganic, organic, and composite materials.
- Summarize research on enhancing the Na metal-electrolyte interface with artificial layers.
Main Results:
- Artificial interface layers offer a promising strategy for stabilizing Na metal anodes.
- Tailored interphases can mitigate dendrite growth and improve Na deposition morphology.
Conclusions:
- Interface engineering is vital for developing safe and high-energy next-generation SMBs.
- Further research into interphase chemistry will advance SMB technology.
