| 英文摘要 | Li-S batteries are regarded as one of the most promising energy-storage devices due to their high theoretical energy density, five times higher than that of lithium-ion batteries (2600 vs. similar to 500 W h kg(-1)). However, the polysulfide shuttle effect is the primary challenge for future applications of Li-S batteries. Herein, a novel barrier layer material, nonstoichiometric W18O49 nanowires, is reported to alleviate the undesirable shuttle effect, thereby largely boosting the specific capacity and cyclability of Li-S batteries. Without particular cathode design, the introduction of W18O49 nanowires enables the commercially available micro-sized sulfur cathode with 70% sulfur loading to deliver a respectable initial discharge capacity of 1142 mA h g(-1) and retain a specific capacity of about 809 mA h g(-1) after 50 cycles, even at a current density of 0.5 A g(-1). To the best of our knowledge, such a capacity fading for Li-S batteries based on high loading of commercial micro-sized sulfur has been rarely reported. |
