  • Publication number: 20190031527
    Abstract: An improved process is provided for forming a precursor to a lithium metal oxide. An improved lithium metal oxide formed by calcining the precursor is also provided. The process includes providing lithium bicarbonate in a first aqueous mixture. The lithium bicarbonate is then reacted with metal acetate thereby forming a second aqueous mixture comprising metal carbonate, lithium acetate, acetic acid and water wherein the acetic acid is neutralized with lithium hydroxide thereby forming a first mixture comprising metal carbonate and lithium acetate. The first mixture is separated into a second mixture and a third mixture wherein the second mixture comprises the metal carbonate and a first portion of lithium acetate with metal carbonate and lithium acetate being in a predetermined molar ratio. The third mixture comprises a second portion of lithium acetate. The second mixture is dried thereby forming the precursor comprising metal carbonate and lithium acetate in the predetermined molar ratio.
