Three dimensional (3D) MoS2/graphene hybrid aerogels have emerged as promising candidates for energy storage and conversion technologies. In this paper, a facile one-pot freeze-drying self-assembly approach combined with in-situ thermal decomposition-reduction method is proposed to construct 3D porous aerogels with MoS2 active materials anchored on graphene backbone, making a highly interconnected network with desirable structural stability. The constructed hybrid aerogels with the optimal MoS2/GS ratio delivered high specific capacities, excellent cycling stability (862.5 mAh g(-1) after 200 cycles at 0.1 A g(-1) with a capacity retention of 109.6%) and good rate capability (622, 563 and 480 mAh g(-1) at 1, 2 and 3 A g(-1), respectively), holding great promise to be used as anode materials of LIBs. More importantly, the current method is simple, low-cost, environmental friendly without any need for toxic reagents, suitable for scalable production and can be extended to prepare other graphene-based hybrid aerogels.
