Definitions
- the purpose of the present invention is to overcome the defects of low first charge and discharge efficiency of the lithium ion battery corresponding to the precursor obtained by the existing coprecipitation crystallization method and cause a huge burden on the environment, and to provide a lithium ion battery that can improve the first charge and discharge of the lithium ion battery.
- each metal may be used in the form of a metal element, or in the form of a metal oxide, and may also be used in a mixed state of the two.
- the Li/Me molar ratio of the environment-friendly precursor and the lithium source is (0.9-1.3):1.
- the metal mixture (the four metals Co, Al, Mg, and Ti are mixed in a molar ratio of 1:0.01:0.004:0.005), nitric acid, high-purity water, and sodium nitrate are added simultaneously in a molar ratio of 10:1:1:4.
- the chemical corrosion crystallization reaction was carried out in the reactor, and 30g/L ammonium nitrate was added at the same time.
- the precursor and composite oxide powder were prepared according to the method of Example 1, except that the metal raw material was replaced by a mixture of five metals, Ni, Co, Mn, Zr and W, with Ni and Mg in a molar ratio of 9.5:0.5.
- the composite oxide powder was designated as QL-9.
- the composite oxide powder obtained in Examples 1 to 9 and the reference composite oxide powder obtained in Comparative Examples 1 to 3 were used as positive electrode materials, and the positive electrode material, conductive carbon black and polyvinylidene fluoride (PVDF) were in a mass ratio of 80: 10:10 was dissolved in NMP solvent under vacuum condition to prepare a positive electrode slurry with a solid content of 70% by weight.
- the positive electrode slurry was coated on the current collector aluminum foil, dried in a vacuum at 120° C. for 12 h, and punched to obtain a positive electrode disk with a diameter of 19 mm.
