Powderous positive electrode material for lithium ion batteries
A recently granted patent (Publication Number: US12002952B2) discloses a powderous positive electrode material designed for lithium-ion batteries. The material consists of crystalline lithium transition metal-based oxide particles with a specific formula and characteristics. These particles have a small crystallite size, determined by X-ray diffraction, and a normalized molar ratio (MR) of Ni in the particle structure. Additionally, the material contains a dopant and has specific ranges for various parameters such as lithium content, transition metal ratios, and carbon content.
Furthermore, the patent claims the positive electrode material can include a secondary phase coating on the particles, with specific compositions and percentages. The dopant used in the material can be selected from a group of elements, and the particle size distribution is also defined within a certain range. The patent also outlines a detailed method for preparing this electrode material, involving specific steps such as preparing a precursor, mixing with lithium compounds, sintering at controlled temperatures and times, and obtaining the final powder material. The method ensures the desired characteristics and composition of the positive electrode material for optimal performance in lithium-ion batteries.
