Reciprocal hybridization of MoO2 nanoparticles and few-layer MoS2 for stable lithium-ion batteries

Abstract

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.
