a Charge–discharge curves of MoS1.5Te0.5@C nanocables||EG dual-ion cell marked by colorful dots in the first cycle. Ex situ XRD patterns of the MoS1.5Te0.5@C nanocables anode (b) and EG cathode (c). d Ex situ Raman spectroscopy of EG cathode. e HRTEM image, f STEM image, g elemental mappings at fully charging state, and h HRTEM image at fully discharging state for MoS1.5Te0.5@C nanocables anode. The ex situ postmortem measurements were carried out on electrodes cycled using the 3 M NaPF6 in EC/EMC/DMC (1:1:1, by volume) electrolyte solution at a specific current of 0.1 A g−1 and 25 °C. i Schematic illustration of the Na+ storage mechanism and electronic conductivity in the MoS1.5Te0.5@C nanocables with stable “nanowire-in-nanotube structure”.
