Abstract: The invention relates to a method for treating used lithium batteries (10) containing the steps: comminuting the batteries (10) such that comminuted material (24) is obtained, and (b) inactivating of the comminuted material (24) such that an inactive comminuted material (42) is obtained. According to the invention, the drying is conducted at a maximum pressure of 300 hPa and a maximum temperature of 80° C. and the deactivated comminuted material (42) is not filled into a transport container and/or said deactivated comminuted material is immediately further processed after the drying process.

Abstract: The invention relates to a method for recycling used lithium batteries containing the steps: (a) digestion of comminuted material (10), which contains comminuted components of electrodes of lithium batteries, using concentrated sulphuric acid (12) at a digestion temperature (TA) of at least 100° C., in particular at least 140° C., so that waste gas (14) and a digestion material (16) are produced, (b) discharge of the waste gas (14) and (c) wet chemical extraction of at least one metallic component of the digestion material (16).

Abstract: A method is described for the treatment of used batteries, in particular lithium batteries, containing the steps: comminuting the batteries such that comminuted material is obtained, inactivating the comminuted material such that inactivated comminuted material is obtained, and filling a transport container with the inactivated comminuted material. The inactivation is performed by drying the comminuted material, and the comminuted material is dried until an electrolyte content is so low that an electrochemical reaction is not possible.

Abstract: A method for retrieving active material from a galvanic cell is provided. The galvanic cell includes an active material, a support for the active material and a binder for bonding the active material and the support. The method includes the following steps: (a) crushing the cells, in particular under inert gas or in a vacuum, so that solid cell fragments are also formed, (b) heating the solid cell fragments up to the decomposition temperature (Tz), which is high enough to make the binder decompose so that it loses its binding properties, preferably under inert gas or in a vacuum, such that heat treated cell fragmented are formed, and (c) classifying the heat treated cell fragments, whereby (d) the classifying comprises air jet sieving and (e) the air jet sieving is carried out in such a way that the active material is separated from the support.
