摘要
Lithium-sulfur batteries due to high theoretical specific capacity and quality of energy density, low-cost advantages are thought to be most likely to next-generation lithium-ion batteries for its production, but its development is shuttle effect, reaction kinetics hysteresis problems such as serious obstacles, the study found that for a moderate amount of polysulfide adsorption and fast catalytic conversion is the key to improve the battery performance. Herein, we synthesized a modified lithium sulfur battery separator for high entropy oxidesy((FeCoNiCrMn)(3)O-4). The synergistic effect between multiple active sites and multi-components of (FeCoNiCrMn)(3)O-4 can strong anchor and catalytic ability for polysulfides, thus can improve the utilization efficiency of sulfur. As (FeCoNiCrMn)(3)O-4 was utilized to modify the separators, the resulting Li-S battery showed an excellent battery performance.
