| titleOfInvention | Three-dimensional porous lithium vanadate anode material and preparation method thereof |
| abstract | The invention discloses a three-dimensional porous lithium vanadate anode material and a preparation method thereof. The three-dimensional porous lithium vanadate anode material comprises a LiV3O8 phase and a Li0.3V2O5 phase, wherein a mass ratio of the LiV3O8 phase to the Li0.3V2O5 phase is (2.12 to 2.80): 1. A primary particle of the three-dimensional porous lithium vanadate anode material is in a shape of a sheet, wherein length of the primary particle is in a range of 100 to 1000 nanometers, width is in a range of 50 to 600 nanometers and thickness is in a range of 10 to 80 nanometers. A secondary particle of the three-dimensional porous lithium vanadate anode material is cubical, wherein length of a side of the secondary particle is in a range of 20 to 40 micrometers. The three-dimensional porous lithium vanadate anode material has an aperture distribution range of 20 to 100 nanometers. The preparation method comprises the following steps of adding LiOH.H2O, NH4VO3 and glycine into deionized water, stirring to mix them, drying the mixture to obtain black precursor powder, and sintering the black precursor powder in an air atmosphere to obtain desired products. The preparation method has the advantages of simple process, safe operation and favorable convenience for industrialized production. The three-dimensional porous lithium vanadate anode material can be utilized for lithium ion battery anode assembled batteries, and has a high charging and discharging capacity and good cycle stability. |
