Title: Partially sulfurized MoO{sub 2} film for durable lithium storage

Abstract

Highlights: • A partially sulfurized MoO{sub 2} (S-MoO{sub 2}) film is grown on Mo substrate. • The hybrid S-MoO{sub 2} film can be directly adapted as Li-storage electrode. • The S-MoO{sub 2} film delivers a high Li capacity of 899 mAh g{sup −1} with good durability. • Self-supported nanostructures are promising for battery application. - Abstract: In this work we present a simple and scalable approach to fabricate highly-active, self-supported molybdenum dioxide (MoO{sub 2}) film for lithium storage. The fabrication is based on a thermal oxidation of Mo foil under air atmosphere and a subsequent sulfurization treatment. A hybrid film composed of partially sulfurized MoO{sub 2} can be produced by controlling the sulfurization conditions. This hybrid film can be directly adapted as binder-free electrode for lithium storage, displaying a reversible capacity of 899 mAh g{sup −1} and a high initial Coulombic efficiency (CE) of 75%. More importantly, the hybrid film sustains 250 successive cycles at a high rate of 10C without evident capacity decay, thereby suggesting its potential for durable battery application.
