The few-layered ultra-small MoS2 nanosheets enhance performance and stability in aluminum-ion batteries by reducing electrostatic repulsion and mechanical stress, increasing active sites exposure, and shortening ion transport distance.
We report novel few-layered ultra-small MoS2 nanosheets, which significantly enhance kinetic performance and structural stability when employed as the cathode in the aluminum-ion battery (AIB). During Al3+ insertion, the few-layered structure weakens the electrostatic repulsion and the small size reduces the mechanical stress. Moreover, the high specific surface area exposes more active sites and increases the contact area between the active material and the electrolyte, shortening the ion transport distance.
