Facile Green Synthesis of Pseudocapacitance-Contributed Ultrahigh Capacity Fe2(MoO4)3 as an Anode for Lithium-Ion Batteries

“…The contribution of the capacitive effect in the enhancement of the specific capacity will be further discussed in the next section. Furthermore, the capacity-increasing performance throughout the continuous charge/discharge process of FMO-ABR, which also has been reported in various previous references regarding transition-metal oxides, ,− could be explained by the following reasons. First, the in situ formation of the metallic particles embedded in the Li 2 O matrix could not only provide additional active sites for the adsorption of lithium ions but could also be favorable for enhancing the electrical conductivity, thereby accelerating the kinetics of the conversion reaction .…”

“…Additionally, this material could be applied as a possible alternative anode for LIBs that could deliver a theoretical capacity up to 1087 mA h g –1 because of constituent high oxidation state elements Fe 3+ and Mo 6+ species . However, the practical applicability of this Fe–Mo binary oxide is limited because the capacity quickly fades upon cycling, originating from its poor electrical conductivity and large volume change during lithiation/delithiation. − To the best of our knowledge, few strategies have been studied and demonstrated as effective methods to overcome these limitations. Some studies have suggested combining the compound with highly conductive materials, such as carbon nanotube and graphene oxide, or assembling as a nanohierarchical structure, which facilitates charge carrier transportation .…”

However, because of the lack of investigations, it is necessary to further study a simple method that can not only enhance the electrical/ionic conductivity but also accommodate the vulnerability of the electrode.…”

Tailoring Oxygen Vacancies in CoMoO4 for Superior Lithium Storage

“…[5] Compared with the individual cobalt oxide and molybdenum oxide, the electrochemical reactivity of the electrode material would be effectively promoted due to the synergistic effect between cobalt and molybdenum. [6,7] For example, Chen and co-workers reported the fabrication of CoMoO 4 /carbon cloth with a high specific capacity of 764 mA h g À 1 after 1000 cycles at 1200 mA g À 1 . [8] Lyu and coworkers prepared the CoMoO 4 @graphene nanosphere, which delivered a high specific discharge capacity of 783 mA h g À 1 after 150 cycles at 0.5 A g À 1 .…”

“…CoMoO 4 draws great attention due to its variable oxidation states and unique d‐electron configuration [5] . Compared with the individual cobalt oxide and molybdenum oxide, the electrochemical reactivity of the electrode material would be effectively promoted due to the synergistic effect between cobalt and molybdenum [6,7] . For example, Chen and co‐workers reported the fabrication of CoMoO 4 /carbon cloth with a high specific capacity of 764 mA h g −1 after 1000 cycles at 1200 mA g −1 [8] .…”
