Suppressing Self-Discharge and Shuttle Effect of Lithium–Sulfur Batteries with V<inf>2</inf>O<inf>5</inf>-Decorated Carbon Nanofiber Interlayer
A study was conducted to demonstrate suppressing of self-discharge and shuttle effect of lithium–sulfur batteries with V2O5-decorated carbon nanofiber interlayer. Coin cells, composed of bare sulfur cathodes, separators, and lithium plates, were assembled by embedding the additional CNF or V2O5-decorated carbon nanofiber (VCNF) interlayers between cathodes and separators to determine the effect of V2O5-decorated interlayer on the electrochemical performances of Li–S batteries. The VCNF/Li battery was also prepared just by capitalizing VCNFs as cathode to ensure the contribution of V2O5 component to the whole capacity of S/VCNF/Li.
