Micrometric Growth of V2O5Hexagonal Nano-plates as an Active Material for Lithium Ion Battery Cathode Electrode
This manuscript reports the synthesis of V2O5 nanostructures using reflux method, without using additives such as surface reactants. The influence of reaction parameters like temperature and concentration on the growth of nanostructures have been investigated. It has been observed that the nanostructures are formed with a hexagonal nano-plate morphology, grown from a common core. The diameter o...
متن کاملAir‐Stable Copper‐Based P2‐Na7/9Cu2/9Fe1/9Mn2/3O2 as a New Positive Electrode Material for Sodium‐Ion Batteries
An air-stable copper-based P2-Na7/9Cu2/9Fe1/9Mn2/3O2 is designed and synthesized by a simple solid-state method and investigated as a positive electrode material for sodium-ion batteries. The attractive long cycling stability is demonstrated by the capacity retention of 85% after 150 cycles at 1 C rate without phase transformation. The reversible Cu2+/Cu3+ redox couple in P2 phase oxides is pro...
متن کاملα-Na2Ni2Fe(PO4)3: a dual positive/negative electrode material for sodium ion batteries.
A new orthophosphate α-Na2Ni2Fe(PO4)3 was synthesized using a solid state reaction route, and its crystal structure was determined from powder X-ray diffraction data. The physical properties of α-Na2Ni2Fe(PO4)3 were studied by magnetic and electrochemical measurements and by Mössbauer and Raman spectroscopy. α-Na2Ni2Fe(PO4)3 crystallizes according to a stuffed α-CrPO4-type structure with the sp...
متن کاملManganese hexacyanomanganate open framework as a high-capacity positive electrode material for sodium-ion batteries.
Potential applications of sodium-ion batteries in grid-scale energy storage, portable electronics and electric vehicles have revitalized research interest in these batteries. However, the performance of sodium-ion electrode materials has not been competitive with that of lithium-ion electrode materials. Here we present sodium manganese hexacyanomanganate (Na2MnII[MnII(CN)6]), an open-framework ...
متن کاملElectrochemical and Structural Study of the Layered, “Li-Excess” Lithium-Ion Battery Electrode Material Li[Li1/9Ni1/3Mn5/9]O2
The overcapacity mechanism and high voltage process of the Li-excess electrode material Li[Li1/9Ni1/3Mn5/9]O2 are studied by solid-state NMR, X-ray diffraction, X-ray absorption spectroscopy, transmission electron microscopy, combined with galvanostatic and potentiostatic intermittent titration electrochemical measurements. The cycling performance is improved noticeably when the material is cyc...
