Title: | Recycling of Spent/Used/Discarded Lithium Iron Phosphate (LFP) Batteries for Recovery of Lithium, Iron, and Phosphorus |
Area: | Chemical Sciences, Earth, Atmosphere & Environment Sciences |
Focus Area: | Recycling of Batteries |
Social Benefits: | Technology can recover lithium in the most desired marketable form, apart from iron phosphate. The derived values can be used for multiple applications apart from new battery manufacturing. |

Brief Description
Description : | With acid leaching using 10-20% solids, 98-100% Li, Fe and P could be extracted. The leach liquor was subjected to a selective sequential precipitation route to extract 90-95% pure lithium as lithium carbonate/lithium hydroxide and 98% pure iron phosphate. Purified graphite was a derivative in the process.
Low-cost acid leaching and low-temperature process
. High pure (>90-95%) lithium product(s)
. High pure 98% iron phosphate
. 85% pure graphite is a by-product
. Easily replicable on a large scale
. Closed-loop recycling of reagents
. Low Incubation time and high returns |
