Breaking insulating barriers in solid-phase conversion reactions with dual-atom catalysts for high-energy lithium batteries (opens in new tab)

Batteries based on redox chemistry, such as lithium–sulfur and lithium–oxygen, can store more energy than conventional lithium-ion batteries. However, their chemical reactions are limited by sluggish and incomplete conversion reactions, especially those involving insulating solid intermediates (for example, Li2S2 and Li2O2), in which electrocatalysts play a decisive role. Here, through a large-scale theoretical analysis, we propose an electronic property criterion that emphasizes the efficien...
