  • Patent number: 11121370
    Abstract: Provided is an improved method for forming lithium ion cathode materials specifically for use in a battery. The method comprises forming a first solution comprising a digestible feedstock of a first metal suitable for formation of a cathode oxide precursor and a multi-carboxylic acid. The digestible feedstock is digested to form a first metal salt in solution wherein the first metal salt precipitates as a salt of deprotonated multi-carboxylic acid thereby forming an oxide precursor. The oxide precursor is heated to form the lithium ion cathode material.

  • Publication number: 20200328415
    Abstract: A method of forming an improved calcined lithium metal oxide is provided wherein the metal comprises at least one of nickel, manganese and cobalt. The method comprises forming a first solution in a first reactor wherein the first solution comprises at least one first salt of at least one of lithium, nickel, manganese or cobalt in a first solvent. A second solution is formed wherein the second solution comprises a second salt of at least one of lithium, nickel, manganese or cobalt in a second solvent wherein the second salt is not present in the first solution. A gas in introduced into said first solution to form a gas saturated first solution. A second solution is added to the gas saturated first solution without bubbling to form a lithium metal salt. The lithium metal salt dried and calcined to form the calcined lithium metal oxide.
