Abstract Lithium-sulfur batteries have been considered as one of the most promising electrochemical power sources due to its extremely high energy density and high theoretical specific capacity. However, poor cycling life due to the dissolution of lithium polysulfides hinders its practical application. In this paper, C60 nanorods are prepared by a facile, scalable and repeatable antisolvent induced precipitation method at an ambient temperature and used as a novel interlayer material for lithium-sulfur batteries. It was proved that C60 nanorods could efficiently inhibit the diffusion of lithium polysulfides via both physical adsorption and strong chemical bonding. Lithium-sulfur batteries with C60 interlayer delivered a capacity of 725 mAh g−1 and a capacity retention of 154.5% after 500 cycles at 4800 mAg−1 with a coulombic efficiency around 100%.

用于高性能锂硫电池的富勒烯纳米棒的简便制备

摘要 锂硫电池由于具有极高的能量密度和较高的理论比容量，被认为是最有前景的电化学电源之一。然而，由于多硫化锂的溶解而导致循环寿命差阻碍了其实际应用。在本文中，C60 纳米棒在环境温度下通过一种简便、可扩展和可重复的反溶剂诱导沉淀方法制备，并用作锂硫电池的新型夹层材料。证明C60纳米棒可以通过物理吸附和强化学键有效抑制多硫化锂的扩散。具有 C60 夹层的锂硫电池在 4800 mAg-1 下循环 500 次后容量为 725 mAh g-1，容量保持率为 154.5%，库仑效率约为 100%。
