Hybrid sp carbon with a graphene backbone and graphitic carbon nanocages (G-GCNs) is demonstrated as an ideal host for sulfur in Li-S batteries, because it serves as highly efficient electrochemical nanoreactors as well as polysulfides reservoirs. The as-obtained S/(G-GCNs) with high S content exhibits superior high-rate capability (765 mA h g at 5 C) and long-cycle life over 1000 cycles.
具有石墨烯骨架和石墨碳纳米笼（G-GCNs）的杂化 sp 碳被证明是 Li-S 电池中硫的理想宿主，因为它既可用作高效的电化学纳米反应器，又可用作多硫化物的储存库。所获得的高硫含量 S/(G-GCNs) 具有出色的高倍率性能（在 5 C 时为 765 mA h g-1）和超过 1000 次循环的长循环寿命。
