Abstract: The invention relates to a device for the thermal or thermo-chemical treatment, more particularly calcination, of material (12), more particularly battery cathode material (14), comprising a housing (16), in which a process space (20) is located. The material (12), or carrying structures (40) loaded with the material (12), can be conveyed in a conveying direction (30) into or through the process space (20) by means of a conveying system (28). A process space atmosphere (50) prevailing in the process space (20) can be heated by means of a heating system (48). There is a process gas system (64), by means of which a process gas (66) can be fed to the process space (20), said process gas being required for the thermal treatment of the material (12).

Abstract: A container for storing a powder mixture during heat treatment in a furnace, a furnace and a method for heat treatment of a powder mixture. The aim of the invention is to specify a container by means of which in particular the throughput per unit of time can be increased and an automatic removal of the container is simplified. This aim is achieved by a plurality of receptacles for releasable fastening of spacers which in the installed state allow contactless stacking of a plurality of containers one above the other.

Abstract: A device for thermal or thermo-chemical treatment, in particular calcination, of material, in particular battery cathode material, having a housing and a process chamber in the housing, in which there is a process chamber atmosphere during the treatment and which defines a conveying level. The material, or carrying structures loaded with the material, at the conveying level can be conveyed in a conveying direction into and/or through the process chamber by a conveying system. An entry airlock gate defines an inlet level and includes an airlock gate chamber, an airlock gate inlet and an airlock gate outlet, as well as an inlet conveyor which is designed so that the material or carrying structures loaded with the material at the inlet level can be conveyed through the airlock gate inlet and into the airlock gate chamber. The conveying level and the inlet level are different from one another.

Abstract: Injection device (56) for discharging a gas (54), in particular a process gas (54), onto a material (12), in particular onto a battery cathode material (14) that is to be calcined, having at least one inlet (58) through which the gas (54) can be supplied to the injection device (56), and at least one outlet (60) through which the gas (54) can be discharged from the injection device (56), the inlet and outlet being connected to one another by a flow path (62) for the gas (54). According to the invention, the flow path (62) has a heat exchanger (64) with a heat exchanger housing (68) which is accessible from the outside for an ambient atmosphere (66) and in which a duct arrangement (70) is integrated. The duct arrangement (70) comprises a first flow duct (72.1) and a second flow duct (72.2) between which there is formed a redirection region (74.1) such that the gas (54) can flow through the first and second flow duct (72.1, 72.2) in different main flow directions.
