  • Patent number: 11881583
    Abstract: A positive electrode active material includes a doped lithium nickel phosphate having an olivine structure comprising distorted NiO6 octahedra. The dopant is an anion; or a combination of at least two transition metals having different ionic radii; or an anion and a metal cation. The positive electrode active material can be used in a positive electrode for an electrochemical cell.
    Type: Grant

  • Publication number: 20230102903
    Abstract: An electrode for a secondary battery includes a current collector; and an active material structure on the current collector, the activate material structure including: at least one first high-density layer, and at least one second high-density layer, the at least one second high-density layer being further away from the current collector as compared to the at least one first high-density layer; and a low-density layer between the at least one first high-density layer and the at least one second high-density layer, wherein a thickness of the at least one second high-density layer is greater than a thickness of the at least one first high-density layer.
