Title:
FLASH RECYCLING OF BATTERIES
Document Type and Number:
WIPO Patent Application WO/2022/170244
Kind Code:
A3
Abstract:
Method and system for flash recycling of batteries, including lithium-ion batteries, other metal (sodium, potassium, zinc, magnesium, and aluminum) -ion batteries, metal batteries, batteries having all metal oxide cathodes, and batteries having graphite-containing anodes. The method and system include a solvent-free and water-free flash Joule heating (FJH) method performed upon a mixture that includes materials from the batteries done in millisecond for recycling the materials.. In some embodiments, the FJH method is combined with magnetic separation to recover lithium, cobalt, nickel, and manganese with high yields up to 98%. In some embodiments, the FJH method is followed by rinsing with dilute acid, such a 0.01 M HCl. In other embodiments, the FJH method is utilized to purify the graphite in the battery, such as for use in the anode of the battery.
