Embodiment Construction

[0026] An exemplary method and apparatus for recycling batteries, such as lithium-ion batteries, is depicted below. The proposed method is an example and is applicable to other lithium and non-lithium batteries for recycling spent batteries and recovering active cathode material suitable for use in new batteries. figure 1 is an environmental diagram of a battery recycling environment 100 suitable for use with the configurations herein. refer to figure 1, in the battery pack recycling environment 100, electronic devices 110 such as laptops, automobiles (hybrid and pure electric), computers, smart phones, and any other type of battery pack supported device are suitable for use with the disclosed method used together. These electronic devices contribute spent batteries 120 that have depleted cathode materials 122 that, however, include raw materials that are responsive to the recycling methods discussed herein. The physical separation process 124 disassembles the battery to fo...

Abstract

Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.

Description

[0001] Statement of Federally Funded Research [0002] This invention was made with government support under grants NSF-1464535 and NSF-1343439 awarded by the National Science Foundation. The government has certain rights in this invention. Background technique [0003] For decades, portable power supplies have taken the form of battery packs that release electrical energy from electrochemical reactions. Various battery pack chemistries, such as conventional "dry cell" carbon flashlight battery packs and lead-acid "wet" batteries commonly found in automobiles, already provide sufficient portable power. However, modern electronics place significantly higher demands on the life and quality of battery packs. Traditionally battery pack power exceeds the required mass of charge material for generating sufficient current. Regular flashlight battery packs only deliver low currents. Automotive battery packs used to deliver intense but brief flows of high amperage to starter motors...
