Abstract

Molybdenum disulfide (MoS2) is one of the most attractive anode materials for lithium-ion batteries (LIBs) due to its high theoretical specific capacity, but its poor cyclic stability need further optimization for its practical application. In this study, porous MoS2/polyaniline (MoS2/PANI) composite with a tremella-like hierarchical structure was synthesized via a facile polymerization and hydrothermal method. The homogeneously distributed PANI can not only improve the conductivity of MoS2, but also rebuild a hierarchical porous structure thus enhance rapid Li+ transport during the Li+ insertion/extraction reaction. As an anode material of LIBs, this composite exhibits a high initial reversible capacity of 910 mAh/g with an initial Coulombic efficiency of similar to 80% at 0.1 A/g. Even at a high current density of 4 A/g, the reversible capacity of the MoS2/PANI composite still remains at 369 mAh/g. Moreover, this composite retains an impressive high capacity of 915 mAh/g after 200 cycles at a high current density of 1 A/g, demonstrating its potential for applications in LIBs.
