Latest Patents

One of her latest patents focuses on a charge material for recycled lithium-ion batteries. This innovative process involves dissolving cathode material from exhausted lithium-ion batteries in a solution to extract useful elements such as cobalt (Co), nickel (Ni), aluminum (Al), and manganese (Mn). The solution contains compounds of these desirable materials, which are derived from the exhausted cathode material of spent cells. By adjusting the proportion of the desired materials, raw materials can be added to achieve the optimal ratio of commingled compounds for the recycled cathode material. This method allows the desired materials to precipitate out of the solution without the need for extensive heating or separation into individual compounds. The resulting active cathode material maintains a predetermined ratio for use in new cells, significantly reducing the high heat typically required for separating useful elements.
