Vertically oriented MoSe0.4S1.6/N-doped C nanostructures directly grown on carbon nanotubes as high-performance anode for potassium-ion batteries

A novel sandwiched hybrid nanoplates vertically anchor on carbon nanotubes. The nanomaterials have facile K-ion intercalation and rapid K-ion transport simultaneously, and can maintain high reversible conversion reaction. The nanomaterials deliver enhanced conductivity and accelerated diffusion kinetics. The as-prepared electrode improves cycle stability and rate performance with reversible capacity.
