Towards Scalable Processing of Amorphous LLZO for Solid State Batteries

Solid-state lithium batteries show promise as a leading technology for next-generation high-energy-density storage, with the ceramic oxide Lithium Lanthanum Zirconium Oxide (LLZO) emerging as a key candidate for solid-state electrolytes due to its high ionic conductivity. However, commercial development has faced significant hurdles in the scalable processing of low-defectivity thin films in a manner suitable for mass-market battery applications. In this defense, I present our research on the formation of amorphous LLZO (a-LLZO) using a blown-arc nitrogen plasma technique to rapidly form thin film a-LLZO, then evaluate the viability of a-LLZO for scalable applications in contrast with the more commonly researched cubic phase.
