2D MoS2/polyaniline heterostructures with enlarged interlayer spacing for superior lithium and sodium storage

We demonstrate the confined synthesis of 2D MoS₂/PANI nanosheets heterostructure with well-defined interfaces, in which the interlayer distance of MoS₂ is enlarged from 0.62 nm to 1.08 nm. The unique structure shows excellent Li/Na storage capability mainly due to the remarkably enhanced Li⁺/Na⁺ diffusion mobility.
