Sandwich-type, two-dimensional hybrid nanosheets were fabricated by the infiltration of nanosized sulfur into graphene-backboned mesoporous carbon with a PPy nanocoating. They exhibit a high reversible capacity for as long as 400 cycles with an ultra slow decay rate of 0.05% per cycle at the high rate of 1-3 C due to the efficient immobilization of polysulfides.
通过将纳米尺寸的硫渗透到具有聚吡咯纳米涂层的石墨烯骨架介孔碳中，制备出三明治型二维混合纳米片。由于多硫化物的有效固定，它们在1-3 C的高倍率下表现出高达400次循环的高可逆容量，且每循环的超慢衰减率仅为0.05%。
