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 nanometers in size.

A team of researchers from institutions in China and the US report the design of a negatively charged graphene composite separator for the effective suppression of the polysulfide shuttling effect in Li-sulfur batteries. A recent study demonstrated “charge environment” as an effective way to mitigate the PS shuttling effect.

A team of researchers from China and Germany have used azulene—a benzene-free and vinyl-free molecule—to polymerize with sulfur to create a cathode material for Li-S batteries. Cycling performance of Az-S and pure sulfur at 0.3 —Chen et al. After cycling for 100 cycles, the capacity remained at 515 mAh g -1.

Electric car batteries are a crucial component in the development of electric vehicles (EVs) and have seen significant advancements in recent years. For example the volumetric energy density of lithium-ion batteries has increased eightfold since 2008, from around 55 watt-hours/litre to 450 watt-hours/litre in 2020.
