Waste lithium batteries have become a research hotspot due to their extremely high resources and hazards. Hygrometallurgical recycling is the main existing method for processing waste lithium battery cathode materials, and the recovery of valuable metal elements from the leaching solutions is the key to hygrometallurgical recovery of waste cathode materials. In this paper, nickel, cobalt and manganese were precipitated from a malic acid leaching solution of high manganese cathode material of waste lithium battery as raw material via ozone oxidation, and the optimal precipitation conditions were obtained. The results show that the precipitation rates of nickel, cobalt, and manganese are 18.2%, 41.5%, and 85.8%, and the contents of nickel, cobalt, and manganese in the ozone precipitation slag are 0.85%, 1.63%, and 41.3%, respectively under the optimal precipitation conditions. The ozone oxidation precipitation slag is a high manganese-based precursor, and the precursor is regenerated into LiMn2O4 cathode material after supplementing lithium. The first discharge specific capacity of this regenerate cathode material is 95.4 mA·h/g, and the first charge-discharge efficiency is 84%. The discharge specific capacity retention rate is 67.4% at a high rate, and the discharge specific capacity retention rate after 100 cycles is 80%.
