Sulfur-functionalized graphene monoliths with a high sulfur fraction (16.8 wt%) were prepared to demonstrate a high capacity (∼400 mA h g-1 at 0.1 A g-1) and ultrafast (∼120 mA h g-1 at 5 A g-1) sodium ion storage. The reversible reaction of -C-Sx-C- with sodium ions contributes to the extra capacity while a 3D graphene network guarantees high rate capability.
制备了具有高硫含量（16.8 wt%）的硫功能化石墨烯整体材料，以展示其高容量（在0.1 A g-1时约为400 mA h g-1）和超快的钠离子存储能力（在5 A g-1时约为120 mA h g-1）。-C-Sx-C-与钠离子的可逆反应有助于提供额外的容量，而三维石墨烯网络则保证了高倍率性能。
