Abstract: Abstract A novel silica@gallium core-shell structure is designed to maximize catalytically active surface gallium for highly efficient electrocatalysis of lithium polysulfides in lithium-sulfur batteries. The fabricated SiO2@Ga/S cathode battery exhibits a high reversible capacity of… read more here.
