Cold sintering manufacturing approach solves fabrication challenge for solid-state electrolytes

https://techxplore.com/news/2025-04-cold-approach-fabrication-solid-state.html

"high temperature hinders production, grain boundaries acting as defects hinder conductive ion transport... small amount of powder loaded in system's center cold sintered using heat, pressure, liquid solvent to create dense highly conductive/ stable polymer-in-ceramic composite... enables high-voltage cathodes, allowing battery to generate more energy... cold sintering also applicable to semiconductor and other manufacturing... future: support for large-scale production and recyclability"
