Аннотация:In this work we present a simple and scalable approach to fabricate highly-active, self-supported molybdenum dioxide (MoO2) 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 MoO2 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⁻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.
