AI Technical Summary

Technical Problem

Lithium metal batteries face issues with dendrite growth, low coulombic efficiency, and safety risks due to the high reactivity of lithium metal, which hinder their commercialization.

Method used

A protective layer composed of alpha lipoic acid (ALA) and sulfur molecules (S8), inorganic sulfides, and inorganic nitrides is formed on the lithium metal negative electrode to stabilize the interface and suppress dendrite growth, enhancing the reversibility of lithium deposition and desorption reactions.

Benefits of technology

The protective layer effectively suppresses dendrite growth, improves coulombic efficiency, and enhances the lifespan and safety of lithium metal batteries by forming a stable interface while minimizing resistance.
