Janus MgAlB 2 MBene: a dipole-engineered anode for ultrafast Li-ion transport and exceptional lithium storage
Janus MgAlB2 MBene is a novel anode material designed to enhance lithium-ion battery performance through dipole engineering. By substituting one Mg layer with Al, the Janus structure creates an asymmetric electronic environment that stabilizes two complete lithium layers. This results in high storage capacity (1470.24 mAhg⁻¹) and extremely fast ion transport with an ultralow diffusion barrier of 17.1 meV.
