Latest Patents

One of Maeda's latest patents involves lithium metal oxide cathode materials and a method to produce them. This method allows for the formation of lithium metal oxides comprised of nickel (Ni), manganese (Mn), and cobalt (Co). The process involves using precursor particulates of Ni and Co that are of a specific size, which enhances the safety and capacity of the resulting lithium metal oxides. Notably, the method enables the creation of lithium metal oxides with a primary particle surface Mn/Ni ratio that exceeds the bulk ratio. Additionally, it facilitates the formation of secondary particles with higher densities, leading to improved cathode densities and battery capacities while maintaining good performance.

Another significant patent by Maeda describes an improved method for making a cathode for lithium ion batteries. This method includes mixing lithium metal oxide and lithium metal phosphate in a solvent, ensuring that the primary particles remain agglomerated into secondary particles of a specific size. The mixture is then coated onto a metal foil, and the solvent is removed to form the cathode. This innovative approach aims to enhance the performance of lithium ion batteries, particularly those with manganese-rich metal compositions.
