They explained that the high Li-ion concentration and the stability of argyrodite are two features that make it attractive as a solid-state electrolyte material. The problem is that the Li-ions are trapped in the cage-like, octahedral structure.“The new solid electrolyte material…has an Li-ion conductivity of 10.
To ice the solid-state cake, they also developed a new method for synthesizing the electrolyte. The new process lopped about 30% off the time needed to synthesize a conventional solid-state electrolyte. “While the conventional solid-state reaction process requires more than several days of processing time, this study proposed a simple synthesis method that combines the nanocrystalline nucleation process and an infrared rapid heat treatment technology to shorten the process time to within 10 hours,” the team reported.Last month, Dr.
If that sounds cumbersome and expensive, it is. “It result[s] in high process costs and battery interface contact issues due to reduced mechanical deformability,” the KIST team notes. The new research describes the successful synthesis of a high-performing solid electrolyte in a “one-pot” process, without the need for added heat, let alone high heat. The process can be carried out at room temperature, under normal pressure, and it can be completed in less than 15 hours.
