  • One-Pot Synthesis for Lithium Ion Battery Cathode Material Precursors
    Publication number: 20210376320
    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.
    Type: Application
    Filed: August 12, 2021
    Publication date: December 2, 2021
    Inventors: Annabelle Wong, Cameron Hodgins, Elahe Talaie Pashiri, Farhang Nesvaderani, O'Rian Reid, Sean Mehta, Stephen A. Campbell, Yingzi Feng
