New paper published on NGC-MXene in Advanced Science

New research paper from our collaboration with Michael Naguib: “Nitrogen-Doped Graphene-Like Carbon Intercalated MXene Heterostructure Electrodes for Enhanced Sodium- and Lithium-Ion Storage” published in Advanced Science.

We’ve developed a novel N-doped graphene-like carbon intercalated Ti₃C₂T_x (NGC-Ti₃C₂T_x) heterostructure. But wait… why would one want to add something in-between the MX-layers, the wonderful interlayer space that should host lithium- and sodium-ion for battery application?

By adding a thin carbon layer, we do not block ion uptake but create additional intercalation sites above and beneath the carbon layer! This yields a reversible specific capacity of 305 mAh/g for sodium-ion batteries and 400 mAh/g for lithium-ion batteries.

Our findings address the critical challenge of low reversible capacity in many MXenes, making a contribution to the field of energy storage materials. By intercalating thin carbon layers into MXene, we provide a promising route to enable enhanced capacity for MXene battery electrodes, backed up both by experimental data and modeling data.
