A high performance lithium-ion battery using LiNa0.02K0.01FePO4/C as cathode material and anatase TiO2 nanotube arrays as anode material
In this paper we report on a lithium ion battery (LIB) based on improved olivine lithium iron phosphate/carbon (LiFePO4/C) as cathode material and LiNa0.02K0.01FePO4/C synthesized by sol-gel method and TiO2 nanotube arrays (TNAs) with an anatase phasesynthesized through anodization of Ti foil as an anode electrode. Crystallographic structure and surface morphology of the cathode and anode mate...
متن کاملA phosphorene-graphene hybrid material as a high-capacity anode for sodium-ion batteries.
Sodium-ion batteries have recently attracted significant attention as an alternative to lithium-ion batteries because sodium sources do not present the geopolitical issues that lithium sources might. Although recent reports on cathode materials for sodium-ion batteries have demonstrated performances comparable to their lithium-ion counterparts, the major scientific challenge for a competitive s...
متن کاملMn3O4-graphene hybrid as a high-capacity anode material for lithium ion batteries.
We developed two-step solution-phase reactions to form hybrid materials of Mn(3)O(4) nanoparticles on reduced graphene oxide (RGO) sheets for lithium ion battery applications. Selective growth of Mn(3)O(4) nanoparticles on RGO sheets, in contrast to free particle growth in solution, allowed for the electrically insulating Mn(3)O(4) nanoparticles to be wired up to a current collector through the...
متن کاملIncommensurate Graphene Foam as a High Capacity Lithium Intercalation Anode
Graphite's capacity of intercalating lithium in rechargeable batteries is limited (theoretically, 372 mAh g-1) due to low diffusion within commensurately-stacked graphene layers. Graphene foam with highly enriched incommensurately-stacked layers was grown and applied as an active electrode in rechargeable batteries. A 93% incommensurate graphene foam demonstrated a reversible specific capacity ...
متن کاملInitial Discharge Capacity of Manganese Cobaltite as Anode Material for Lithium Ion Batteries
Nanostructured manganese cobalt oxide spinel (MnCo2O4) are prepared by co-precipitation method and calcined at 650 and 750°C. Morphological studies show that by increasing the calcination temperature from 650 to 750°C, morphology of the particles changes from quasi-plate to polyhedral. The MnCo2O4 calcined at 650°C could deliver an initial discharge capacity of 1438 mAh g-1 under current densit...
