Reciprocal hybridization of MoO ₂ nanoparticles and few-layer MoS ₂ for stable lithium-ion batteries

The reciprocal hybridization of MoO2 nanoparticles and few-layer MoS2 has been realized via a facile hydrothermal reaction. The resulting MoO2/MoS2 hybrids exhibit a high reversible specific capacity of 1103 mA h g(-1) at 0.2 A g(-1) with a high rate performance (273 mA h g(-1) at 6.4 A g(-1)) and an excellent cycling stability (∼92% capacity retention after 800 cycles) mainly due to the strong synergistic effect between them.
