abstract = {Lithium–sulfur batteries are considered important devices for the power of movable equipment, but there are still some challenges that limit their applications, such as how to obtain a cathode for high sulfide adsorption and rapid conversion. Here, a new strategy is proposed to enhance the performance of lithium–sulfur batteries by growing 3-dimensional hydrogen-substituted graphdiyne (HsGDY) layers on Ni foam via Glaser cross-coupling reaction to anchor MoS2/Ni3S2, enhancing the conductivity of host material of S. The results show that the 3-dimensional HsGDY framework enables the fast adsorption of lithium polysulfides and the Ni3S2/MoS2 performs as the reaction center with a low charge transfer resistance. The charge capacity of Ni@HsGDY/MoS2/Ni3S2 cell is up to 1,234.7 mAh·g−1 at the first circle, and the specific capacity keeps 486 mAh·g−1 after 500 cycles at a current density of 2 C. The incorporation of HsGDY into the cathode promotes the adsorption and the conversion of polysulfides, paving a path to obtain lithium–sulfur batteries with high energy density.}
