Abstract

See full text

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.
