Large-Scale Production of MoO 3 -Reduced Graphene Oxide Powders with Superior Lithium Storage Properties by Spray-Drying Process

“…Nanostructured MoO 3 materials such as nanorods, nanoparticles, yolk-shell particles, and hollow spheres have shown superior electrochemical properties as anode materials for LIBs [48][49][50][51][52][53][54]. The electrochemical properties of MoO 3 -graphene composite materials prepared by liquid solution and gas-phase reaction methods have also been studied [35,[54][55][56].…”

Self‐Assembly Approach for Synthesis of Nanotubular Molybdenum Trioxide/Titania Composite Anode for Lithium‐Ion Batteries

“…The initial discharge and charge capacities of MoO 3 ‐76 %‐TiO 2 were 1126.2 and 689.0 mAh g −1 , respectively; and the corresponding Coulombic efficiency was 61.2 %. The large irreversible capacity loss in the first cycle is common for metal oxide based anode materials due to decomposition of the organic electrolyte to form the SEI film and the irreversible intercalation of lithium ions into the crystalline lattices of the metal oxide . The discharge capacities of this composite were seen to decline gradually over the next 50 cycles (from 710.6 to 441.5 mAh g −1 ), and then increased to 483.3 mAh g −1 after 100 cycles.…”

[57,77] Fort he nanotubularM oO 3 -64 %-TiO 2 and MoO 3 -87 %-TiO 2 composites ( Figure S9 in the Supporting Information), the first cycle discharge capacities were 1065.8 and 1460.0 mAh g À1 ,a nd the corresponding Coulombic efficiencies were 56.9a nd 56.6 %, respectively.…”
