Balancing surface adsorption and diffusion of lithium-polysulfides on nonconductive oxides for lithium–sulfur battery design

Metal oxides can suppress detrimental polysulfide shuttling in lithium-sulfur batteries, however selection criteria for oxide materials are still lacking. Here, the authors investigate polysulfide adsorption and diffusion on metal oxides and propose selection criteria based on balancing these two ef...

Sumario:Metal oxides can suppress detrimental polysulfide shuttling in lithium-sulfur batteries, however selection criteria for oxide materials are still lacking. Here, the authors investigate polysulfide adsorption and diffusion on metal oxides and propose selection criteria based on balancing these two effects.
