Exploring the physicochemical role of Pd dopant in promoting Li-ion diffusion dynamics and storage performance of NbS at the atomic scale.

The two-dimensional layered niobium disulfide (NbS), as a kind of anode material for Li-ion batteries, has received great attention because of its excellent electronic conductivity and structural stability. However, its ionic conductivity is far from desirable. Herein, we have proposed an effective way to acquire the rapid promotion of its Li-ion diffusion dynamics from the palladium doping effect.
