The practical application of Li–S batteries remains a challenge because of capacity decay and polysulfide shuttle. This paper reports a highly wrinkled NiO nanosheet-based hierarchical structure that can efficiently restrain the polysulfide shuttle via physical and chemical confinement. Reduced fluorographene–NiO/S (RFG–NiO/S) composites are also prepared by hydrothermal method and thermal treatments. In comparison with NiO/S and RFG/S, the developed hybrid composite of RFG–NiO/S exhibits better initial reversible discharge capacity of 995 mAhg⁻¹, retains 640 mAhg⁻¹ after 110 cycles at 0.1 C, and shows the specific capacity of 381 mAhg⁻¹ at the higher current rate of 0.5 C after 200 cycles.

由于容量衰减和多硫化物穿梭，锂锂电池的实际应用仍然是一个挑战。本文报道了一种高度起皱的基于NiO纳米片的分层结构，该结构可以通过物理和化学限制有效地抑制多硫化物的穿梭。还可以通过水热法和热处理来制备还原性的石墨烯-NiO / S（RFG-NiO / S）复合材料。与NiO / S和RFG / S相比，已开发的RFG–NiO / S混合复合材料表现出更好的995 mAhg ^-1的初始可逆放电容量，在0.1 C下110次循环后仍保持640 mAhg ^-1，并显示出比容量200次循环后，在0.5 C的较高电流速率下，电池的mAh值为381 mAhg ^-1。
