- LITHIUM-RICH MANGANESE-BASED CATHODE MATERIAL ITS PREPARATION METHOD AND LITHIUM-ION BATTERY

摘要

The present invention discloses a method for producing a lithium-rich manganese-based cathode material. The method comprises dispersing the? -MnO ₂ microparticles, the nickel salt and the lithium-containing compound in a solvent to obtain a mixture, then evaporating the mixture to remove the solvent and calcining the solid product obtained from the evaporation ; Wherein the lithium-containing compound is a lithium salt and / or lithium hydroxide. The present invention also provides a lithium-rich manganese-based cathode material prepared by the above method. The present invention also provides a lithium-ion battery wherein the anode material contains the lithium-rich manganese-based anode material. The lithium-rich manganese-based cathode materials provided by the present invention have high rate characteristics and extended cycle stability.
