Abstract

The discovery and design of materials for Li-ion batteries are essential for increasing battery energy storage capacity and lifetime, enhancing security, and shortening charging time. Recently, novel two-dimensional materials have been investigated for application in battery components, including the anode. The limiting factors in the development of these materials are their low structural stability upon Li+ adsorption, propensity to form Li dendrites, and slow diffusion of Li+ ions. In this study, based on density functional theory calculations, we show that the two-dimensional material 2H-NbS2 has outstanding physical properties for application in Li-ion batteries, including high structural stability with Li+ adsorption and ultrafast Li diffusion at room temperature. These results highlight the promise of 2H-NbS2 as an appealing material for Li-ion batteries. (AU)
