Tailoring Nitrogen Terminals on MXene Enables Fast Charging and Stable Cycling Na-Ion Batteries at Low Temperature.

ABSTRACT: Sodium-ion batteries stand a chance of enabling fast charging ability and long lifespan while operating at low temperature (low-T). However, sluggish kinetics and aggravated dendrites present two major challenges for anodes to achieve the goal at low-T. Herein, we propose an interlayer confined strategy for tailoring nitrogen terminals on Ti₃C₂ MXene (Ti₃C₂-N_funct) to address these issues. The introduction of nitrogen terminals endows Ti₃C₂-N_funct with large interlayer space and charge redistribution, improved conductivity and sufficient adsorption sites for Na⁺, which improves the possibility of Ti₃C₂ for accommodating more Na atoms, further enhancing the Na⁺
