Unleashing the Potential of NASICON Materials for Solid-State Batteries

Solid-state batteries (SSBs) represent a transformative technology with the potential to redefine energy storage in various applications, including portable electronics, electric vehicles, and renewable energy systems. However, the intricate interplay of materials and interfaces within SSBs poses significant challenges in realizing their full potential. In this perspective, we highlight the potential of integration of NASICON (Sodium Superionic Conductor) materials into SSB architectures to address compatibility issues and enhance overall performance. We also showcase that, by employing machine learning techniques and a data-driven approach, structure-function relationships governing NASICON materials’ ionic conductivity can be perceived. This eliminates the need for computationally intensive first-principles calculations and offers insights into the mechanism of improving ion transport. Our findings highlight the promise of NASICON-type materials in overcoming chemical, mechanical, and electrochemical disparities at interfaces and interphases, offering a promising path forward for the development of high-performance SSBs.
