  • SINTERED CATHODE ACTIVE MATERIAL BRICKS AND METHODS THEREOF
    Publication number: 20230343923
    Abstract: Disclosed are self-standing calcined elements (e.g. bricks and tiles) comprising a cathode active material, and methods of preparation thereof. The process includes mixing a reagent with a metal precursor to form a precursor mixture, compressing the precursor mixture into a self-standing precursor element (e.g. brick and tile), and heating the self-standing precursor element (e.g. brick and tile) to form a self-standing calcined element (e.g. brick and tile) comprising a cathode active material.
