Metal Oxides Based Nanocomposites for Lithium-Sulfur Batteries

Recently, rechargeable lithium–sulfur (Li–S) batteries gained tremendous attention due to their greater capacity and more affordable price as compared to other battery types. Moreover, lithium-sulfur batteries have many advantages over lithium-ion batteries, the high cathode volume, insulation of sulfur species, shuttle effect of polysulfides and formation of lithium dendrites have a negative impact on the performance and capacity of lithium-sulfur batteries. Due to sulfur's poor electronic conductivity, Li–S batteries can only operate at a restricted pace and for a limited number of cycles. It has been suggested that the rational design of Metal Oxides based nanocomposites cathodes is a viable way to boost sulfur usage and enhance cycle performance of Li–S batteries. We will review the most current developments in Metal Oxides based nanocomposites for Li–S battery cathodes here. On the future of Metal Oxides based nanocomposites cathodes for high performance Li–S batteries, some insights are also provided.
