Lithium sulfur battery is one of next generation energy storage devices because of its excellent electrochemical properties, natural abundance, low cost, eco-friendly, light weight and high energy density. Although there are many advantages, dissolution of lithium poly sulfide into organic electrolytes results in poor cycle performance and rate property of lithium-sulfur batteries. MOFs are excellent porous materials for energy storage and conversion devices, which prevent the dissolution of lithium polysulfides into the electrolyte. And MOFs have low electrical conductivity, which were supplemented by adding graphene oxide. In this study, we investigated the effects of MOFs on the electrochemical properties through heat treatment at different temperatures and the addition of different concentrations of graphene oxide. |
