Producing Printable Na-based Solid-state Electrolyte Thin Using Open-air Processing

Lithium-ion batteries face environmental and economic challenges due to resource scarcity and complex manufacturing. Sodium-based solid-state electrolytes (SSEs) offer a sustainable alternative, but current fabrication methods are costly and inefficient. This work uses an open-air blade coating process for NASICON (Sodium Superionic Conductor)-based SSE thin films. The properties being optimized of the NASICON films are adhesion:  form consistency in film coverage and thickness conductivity for effective ion conduction, and phase for a uniform crystal structure that ensures the material is properly formed.
