dc.description.abstract A graphene-attached VS4 composite prepared by a simple hydrothermal method is studied in terms of its lithium reaction mechanism and high rate capability. The nanocomposite exhibits a good cycling stability and an impressive high-rate capability for lithium storage, delivering a comparable capacity of 630 and 314 mA h g-1, even at high rates of 10 and 20 C (=10 and 20 A g-1, or 10 and 20 mA cm-2), respectively. In addition, full-cell (LiMn2O4/VS4-graphene) test results also exhibited a good capacity retention. The mechanism of Li storage is systematically studied and a conversion reaction with an irreversible phase change during the initial discharge-charge process is proposed. ko
