Three-dimensional MoS₂/Graphene Aerogel as Binder-free Electrode for Li-ion Battery.

ABSTRACT: Hybrid MoS₂/reduced graphene aerogels with rich micro-pore are fabricated through a hydrothermal method, followed by freeze-drying and annealing treatment. The porous structure could act as an electrode directly, free of binder and conductive agent, which promotes an improved electron transfer, and provides a 3D network for an enhanced ion transport, thus leading to an increased capacity and stable long cycle stability performance. Notably, the specific capacity of MoS₂/reduced graphene aerogel is 1041 mA h g^-1 at 100 mA g^-1. Moreover, reversible capacities of 667 mA h g^-1 with 58.6% capacity retention are kept after 100 cycles. The outstanding performance is beneficial from the synergistic effect of the MoS₂ nanostructure a
