Electrochemical lithium insertion into (MoS2)n nanotube bundles

Abstract

It is shown that the (MoS2)n nanotube bundles are capable of reversible lithium insertion. Comparing its properties with layered MoS2, which has been used as a positive material in the Li‐ion batteries in the past [1], the new material shows promising improvements. The intercalation takes place close to the metallic lithium potential and during the insertion process, the potential decreases linearly with the amount of inserted lithium. In all, the system’s characteristics indicate that (MoS2)n nanotubes may be used as a negative electrode in rechargeable lithium batteries with some potential advantages over other systems currently in use.
