(a) Digital images of the Li2S8 trapping by the metal oxide nanoparticles in DOL/DME (1:1, v-v) solution. (b) Experimental and simulated adsorption amount of Li2S8 on different metal oxides. The simulated adsorption was based on the monolayer adsorption model. (c) Optimized geometries of the most stable Li2S on CeO2(111), Al2O3(110), La2O3(001), MgO(100) and CaO(100) surfaces. (d) Optimized geometries of most stable Li2S8 on the metal oxide surface.
