Current density is also ten times higher than without that new spreadable interlayer.
Can a solid-state battery be considered as such if its solid layers are anointed with a butter-like material? For scientists from four different universities, that can be the answer to making these batteries more stable and ten times more current dense, as a study published at Advanced Functional Materials has revealed.
The butter-like material is far from any dairy product: it is a combination of ionic liquid electrolyte and LAGP (Li1.5Al0.5Ge1.5(PO4)3) nanoparticles. The magic happens when it is placed between the solid electrolyte – made of NASICON – and the lithium anode.
NASICON is the acronym for sodium (Na) Super Ionic CONductor. It is one of the most promising solid electrolytes for solid-state batteries because its conductivity can match that of liquid electrolytes.
