Injection device () for discharging a gas (), in particular a process gas (), onto a material (), in particular onto a battery cathode material () that is to be calcined, having at least one inlet () through which the gas () can be supplied to the injection device (), and at least one outlet () through which the gas () can be discharged from the injection device (), the inlet and outlet being connected to one another by a flow path () for the gas (). According to the invention, the flow path () has a heat exchanger () with a heat exchanger housing () which is accessible from the outside for an ambient atmosphere () and in which a duct arrangement () is integrated. The duct arrangement () comprises a first flow duct () and a second flow duct () between which there is formed a redirection region () such that the gas () can flow through the first and second flow duct () in different main flow directions. The invention further relates to a process gas system () for supplying a gas () and to a device () and a method for the thermal or thermo-chemical treatment of material.

Injection device for discharging a gas, process gas system for supplying a process gas, and device and method for the thermal or thermo-chemical treatment of material

The invention relates to a device for the thermal or thermo-chemical treatment, more particularly calcination, of material (), more particularly battery cathode material (), comprising a housing (), in which a process space () is located. The material (), or carrying structures () loaded with the material (), can be conveyed in a conveying direction () into or through the process space () by means of a conveying system (). A process space atmosphere () prevailing in the process space () can be heated by means of a heating system (). There is a process gas system (), by means of which a process gas () can be fed to the process space (), said process gas being required for the thermal treatment of the material (). The process gas system () comprises a plurality of local injection units (), which are arranged and configured such that process gas () can be released in a targeted manner onto the material () or onto the carrying structures () loaded with material (), the process gas being released in a plurality of local process gas streams (), each having a main stream direction (). The invention also specifies a method for the thermal or thermo-chemical treatment of material (), in which process gas () is released in a targeted manner onto the material () or onto the carrying structures () loaded with material (), the process gas being released in a plurality of local process gas streams (), each having a main stream direction ().

Device and method for thermal or thermo-chemical treatment of material

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.
