  • CATHODE WITH DISORDERED ROCKSALT MATERIAL AND METHOD OF FORMING THE CATHODE
    Publication number: 20240097108
    Abstract: A method for forming a cathode includes milling a suspension of precursors via a micromedia mill to form a mixture of primary particles in the suspension. The precursors include one or more metal compounds. The method includes spray drying the suspension after the milling to form secondary particles. The secondary particles are agglomerations of the primary particles. The method also includes annealing the secondary particles to form a disordered rocksalt powder.
