摘要

锂硫电池在下一代储能系统中具有巨大的应用潜力。然而,多硫溶解和再沉积导致循环稳定性差,硫利用率低,速率性能差,从而限制了它们的实际应用。本文采用溶胶-凝胶法制备了Ti_4O_7导电金属氧化物,并将其部分添加到锂硫电池正极中。结果表明,添加7.5 wt% ~ 10 wt%的Ti_4O_7作为导电添加剂,由于Ti_4O_7具有较高的电子导电性和对多硫化物的表面吸附能力,具有较好的速率性能和可逆循环性能。与复杂的结构和复杂的合成方法相比,我们报告了一种更有效的方法来克服锂硫电池的缺点。图形抽象

Ti_4O_7 as conductive additive in sulfur and graphene-sulfur cathodes for high-performance Lithium-sulfur batteries with a facile preparation method
Lithium-sulfur batteries have significant potential to be applied in next-generation energy storage systems. However, polysulfide dissolution and redeposition have contributed to poor cycling stability, low sulfur utilization, and poor rate performance, thereby limiting their practical applications. Herein, we used a sol-gel method to fabricate a Ti_4O_7 conductive metal oxide, which was partially added to a Lithium-sulfur battery cathode. The results demonstrated that the addition of 7.5 wt% to 10 wt% Ti_4O_7 as the conductive additive resulted in a better rate capability and reversible cycling performance owing to its high electronic conductivity and surface adsorption of polysulfides. Compared to complex architectures and complicated synthesis methods, we report a more effective way to overcome the drawbacks of Lithium-sulfur batteries. Graphical abstract
