▎ 摘  要

Sandwich-type, two-dimensional hybrid nanosheets were fabricated by the infiltration of nanosized sulfur into graphene-back-boned 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.
