Engineering Oxygen-Terminated Hexagonal MBene for Accelerated Lithium Migration and Exceptional Lithium-Ion Battery Performance.

ABSTRACT: Ultrathin 2D hexagonal transition metal borides (h-MBenes) hold significant promise for advancing energy storage technologies. Herein, with cost-effective methods and earth-abundant metals, the experimental feasibility of atomically thin Ti-based 2D h-MBenes (TiBT_x) for lithium-ion battery application is reported for the first time. These thin-layer nanosheets are synthesized by using ZnCl₂ molten salt as Ti₂InB₂ etchant, followed with a delaminated intercalation of tetrabutylammonium hydroxide (denoted as d-TiBT_x). The formation of disorderly low-boiling-point Zn-In intermediate phase is revealed to significantly reduce the In migration energy barrier and accelerate the lattice-In release from parent Ti₂InB₂ unde
