titleOfInvention | Method for preparing lithium-enriched solid solution cathode material by two-section direct temperature-rise sintering |
abstract | The invention relates to a method for preparing a lithium-enriched solid solution cathode material by a two-section direct temperature-rise sintering method, which is characterized in that a preparation process comprises the following steps of: respectively weighing a lithium compound, a nickel compound, a manganese compound, a cobalt compound and an oxidant according to the mol ratio of a lithium ion to a nickel ion to a manganese ion to a cobalt ion to a reducing agent of (1+x): (1-x)*y: (x+z-x*z): (1-x)*k: q; mixing the oxidant with a wet milling medium; then mixing the lithium compound, the nickel compound, the manganese compound and the cobalt compound, which are weighed; after wet milling and mixing, adding aqueous ammonia and the lithium compound; then carrying out wet milling and mixing again; ageing and utilizing a heating and drying method to prepare a dry precursor 2; placing the precursor 2 into air, oxygen-enriched gas or pure oxygen atmosphere; and utilizing the two-section direct temperature-rise sintering method to prepare the lithium-enriched solid solution cathode material. An electrode material prepared by the method disclosed by the invention is uniformly formed and has a very good discharging performance; and particularly, the electrode material has the excellent circulating discharging performance under a large-current condition. |
