Abstract
Disclosed herein are a plant for recycling lithium ion battery materials, in particular lithium ion batteries, and a process for recovering valuable materials from lithium ion battery material.
Claims14
A plant for recycling lithium ion battery material, comprising:
- a comminuting device configured to comminute lithium ion battery material in a comminuting space;
- an intermediate storage device arranged downstream of the comminuting device and comprising an intermediate storage space with stirring means;
- a drying device arranged downstream of the intermediate storage device and comprising a drying space with stirring means;
- a pyrolysis device , arranged downstream of the drying device, configured to pyrolyze the comminuted and dried lithium ion battery material in a pyrolysis space;
- and
- at least one screening device configured to separate individual components of the comminuted lithium ion battery material from one another.

A process for recycling lithium ion battery material comprising
- a) providing lithium ion battery material to a comminuting device,
- b) comminuting the lithium ion battery material in the comminuting device,
- c) transferring the comminuted lithium ion battery material into a drying device,
- d) drying the comminuted lithium ion battery material,
- e) transferring the comminuted and dried lithium ion battery material into a pyrolysis device, and
- f) heating the comminuted and dried lithium ion battery material to a temperature of from 400° C. to 630° C. while contacting the comminuted and dried lithium ion battery material with an inert gas and with a reductive gas generated in situ by thermal decomposition of the comminuted and dried lithium ion battery material to obtain a pyrolyzed lithium ion battery material.
