Application: Process for efficient recycling of cathode active materials (Patent ID: US20240097225A1)

The patent filed by Nano One Materials Corp. describes a process for forming recycled cathode active material from depleted cathode active material in a battery. The process involves forming a black mass from the depleted material, digesting it with a carboxylic acid to create a delithiated cathode active material precursor, adding virgin lithium salt to form a cathode active material precursor, and calcining it to produce the recycled cathode active material. The patent also includes specific formulas and ratios for the cathode active materials, as well as details on the selection of dopants and the addition of virgin metal salts during the process.

Overall, the patent outlines a detailed and systematic method for recycling cathode active material from batteries, emphasizing the use of specific carboxylic acids, lithium salts, and calcination processes. The claims within the patent cover various aspects of the recycling process, including the composition of the cathode active material, the ratios of different elements, and the addition of specific dopants. The patent also extends to the formation of batteries using the recycled cathode active material, highlighting the potential for sustainable and environmentally friendly battery production methods.
