Positive electrode active material for batteries with specific composition ratios
The patent application (Publication Number: US20240038982A1) describes a positive electrode active material for lithium-ion rechargeable batteries. The material is a powder containing Li, M', and oxygen, with M' consisting of Ni, Co, Mn, and D elements. The content of these elements is specified within certain ranges, along with the presence of Al and B elements. The material's composition is determined by ICP and XPS analysis, with specific ratios of AlB/AlA, BB/BA, and WB/WA required for the material to meet the patent's criteria. Additionally, the material must have a single-crystalline structure and a median particle size within a specified range.
Furthermore, the patent includes claims related to the ratios of AlB/AlA, BB/BA, and WB/WA, with specific ranges provided for each ratio. The material must also contain Al, B, and W elements in certain minimum quantities, as measured by ICP analysis. The patent extends beyond just the material itself, with claims covering battery cells containing the material and various electronic devices and energy storage systems utilizing the positive electrode active material. Overall, the patent application outlines a detailed composition and characteristics required for a positive electrode active material suitable for lithium-ion rechargeable batteries, with specific ratios and element contents crucial for meeting the patent's specifications.
