Abstract
The present disclosure provides an apparatus for a chlorination method to recycle metal elements in lithium batteries.
Claims18
An apparatus for a chlorination method to recycle metal elements in lithium batteries, comprising:
- a first device for pretreating lithium batteries, configured to remove organic components in the lithium batteries;
- a second device for pretreating lithium batteries, configured to obtain a mixture of powders containing positive-electrode materials;
- a chlorination furnace, configured to heat and chlorinate the mixture of powders at a heating temperature of no less than 500° C.;
- a gas outlet of the chlorination furnace connected to an inlet of a first gas-solid filtration device;
- a gas outlet of the first gas-solid filtration device is connected to a first desublimation device, wherein the first desublimation is set to be below 306° C. and above 178° C.;
- and
- a gas outlet of the first desublimation device connected to a second desublimation device;
- wherein the second desublimation is set to be below 178° C.
