Vanderbilt researchers find iron pyrite quantum dots boost performance of sodium-ion and Li-ion batteries

Green Car Congress

nm, average) of iron pyrite (FeS 2 ) nanoparticles are advantageous to sustain reversible conversion reactions in sodium ion and lithium ion batteries. In this work we explore the sodium and lithium conversion of ultrafine FeS 2 nanoparticles, with a tight size distribution centered around ∼4.5 —Anna Douglas.

Fraunhofer develops new dry-coating process for battery electrodes

Green Car Congress

It could equally be used on lithium-ion cells as on lithium-sulfur or sodium-ion cells. This project demonstrated that it is possible to manufacture electrodes continuously, regardless of the type of battery. The range of possible uses for the technology is not limited to a particular cell chemistry.
