Publication number: 20250019256Abstract: There is provided a method of manufacturing a disordered rocksalt-cathode active material of Formula 1: Li0.4+xM1yM2zO2?kFk??(1) Wherein, 0<x?1.6, 0?z?1, 0?k?0.660<y?1 and (x+y+z)?1.6, and wherein M1 is a redox center selected from Mn, Ni, V, Co, Fe, Ir, Cr, Ru, Mo, and combinations thereof, and M2 is a d0 transitional metal selected from Ti, Zr, V, Nb, Sn, Mo and combinations thereof. The value of y is determined for a species of M1 based on a selection of the other parameters in order to maximize the electrical conductivity. Mathematical simulations that leverage the polaron energy barrier are used to determine the percolation probability and the accessibility of M1 in the percolation network. This allows to select for values of y to obtain a proportion of accessible M1 of at least 90% to improve electrical conductivity and manufacture the active material accordingly.Type: ApplicationFiled: July 11, 2024Publication date: January 16, 2025Inventors: Jinhyuk LEE, Dong Hwa SEO, Eun Ryeol LEE, Dae-Hyung LEE, Sang Wook PARK
