Lithium-sulfur batteries hold great potential for next-generation energy storage systems, due to their high theoretical energy density and the natural abundance of sulfur. Although much progress has been achieved recently, the low actual energy density of Li-S batteries is still the key challenge in implementing their practical applications. Because the energy density greatly depends on the areal capacity of their sulfur cathodes, the sulfur content and sulfur loading play an important role in meeting the conditions necessary for practical applications. Therefore, escalating the areal capacity of sulfur cathodes is essential to promote Li-S technology from laboratory-scale devices to industrial (or commercial) systems. In this review, the recent progress in high sulfur loading of Li-S batteries (>4 mg cm−2) is highlighted from various aspects, including sulfur hosts, binders, separators, and interlayers. In particular, sulfur hosts derived from carbon, polymer, transition metal ox

The NiS2 nanosheet array on Ni foil (NiS2/NF) was prepared using an in situ growth strategy and sulfidation method and was used as the cathode of lithium sulfur battery. The unique nanostructure of the NiS2 nanosheet array can provide abundant active sites for the adsorption and chemical action of polysulfides. Compared with the sulfur powder coated pure NF (pure NF-S) for lithium sulfur battery, the sulfur powder coated NiS2/NF (NiS2/NF-S) electrode exhibits superior electrochemical performance. Specifically, the NiS2/NF-S delivered a high reversible capacity of 1007.5 mAh g−1 at a current density of 0.1 C (1 C= 1675 mA g−1) and kept 74.5% of the initial capacity at 1.0 C after 200 cycles, indicating the great promise of NiS2/NF-S as the cathode of lithium sulfur battery. In addition, the NiS2/NF-S electrode also showed satisfactory electrochemical performance when used as the cathode for sodium sulfur battery.
