Abstract
A MoS<sub>2</sub>/MoO<sub>2</sub> heterointerface is created, with MoO<sub>2</sub> nanocrystals anchored on MoS<sub>2</sub> nanosheets, assisted by an N-doped carbon protecting layer, on CNTs. The electrode has a high specific capacity of ∼700 mA h g<sup>−1</sup> at 0.2 A g<sup>−1</sup>, excellent cycling stability and rate capability.
