Definitions

  • the invention relates to a container and a method for transporting and storing a moisture-sensitive material, in particular battery cell components, in particular electrode material, electrolytes or the like.
  • the invention further relates to the use of a container for transporting and storing a moisture-sensitive material, in particular battery cell components, in particular electrode material, electrolytes or the like.
  • accumulators or secondary/rechargeable battery storage systems or battery cells or battery modules such as lithium-ion accumulators
  • the battery cell components required for their production having to be transported safely within the company or across plants, depending on the process.
  • the transport or handling of an electrode material that regularly has to be processed in a clean room or dry room atmosphere with a comparatively low dew point of approximately ⁇ 60° C. is particularly critical.
  • the electrode material or electrode semi-finished product is usually wound up into a coil or electrode coil and then transported to a location where a next production step is carried out or to a third-party manufacturer. During transport, it is essential to avoid contamination of the electrode material through moist air or moisture.
  • the present invention is therefore based on the object of providing a container and a method for transporting and storing a moisture-sensitive material, in particular battery cell components, in particular electrode material, electrolytes or the like. and to propose the use of a container for the transport and storage of a moisture-sensitive material, in particular battery cell components, in particular electrode material, electrolytes or the like, which is a safe or damage-free, simple, sustainable and cost-optimized transport and storage option creates.
  • the container according to the invention for the transport and storage of a moisture-sensitive material, in particular battery cell components, in particular electrode material, electrolytes or the like comprises a transport space that can be closed in a gas-tight manner with respect to the environment, the container being connectable to a supply device for supplying the transport space with a gas.
  • a container intended for reuse is provided for the transport and storage of the electrode material, so that ongoing costs for the constant procurement and disposal of packaging material are completely eliminated.
  • the packaging of the electrode material in the container intended for reuse is sustainable.
  • the container according to the invention can be used for transporting and storing or packaging a moisture-sensitive material, in particular in battery cell and electronics production.
  • the container according to the invention can be used advantageously for transporting and storing battery cell components, in particular an electrode material or an electrode material wound up to form a coil or an electrode coil or a stacked cell stack.
  • the container has a transport space into which the electrode material can be introduced very easily or in which the electrode material can be arranged very easily, with the container then being able to be closed without the need for complex and time-consuming packaging.
  • unpacking turns out to be comparatively simple, since the electrode material can be easily removed from the container after the container has been opened.
  • the transport space can be closed or locked in a gas-tight or airtight manner with respect to the environment in order to prevent humid ambient air or moisture contained in the ambient air from penetrating into the transport space and consequently contamination of the electrode material accommodated in the transport space by the moisture.
  • the container can also be connected to a supply device or an air module for supplying the transport space with a gas or with air or for forming and/or maintaining a dry atmosphere in the transport space.
  • the container can have a connection to which the supply device can be connected.
  • the gas or air can be such that only little or no hydrogen and/or oxygen is or can be bound in it, so that there is little or no moisture in the transport space or deposited on the electrode material can.
  • the gas can be an inert gas or dry air.
  • the gas can also be a gas mixture.
  • the container according to the invention By means of the supply device, the gas can be fed into the container or transport space and thereby form an overpressure in the transport space relative to the environment, as a result of which penetration of moisture into the transport space can be prevented in order to protect the electrode material from contamination by moisture .
  • the container according to the invention Due to the combination of the supply device with the gas-tight design of the transport space, the container according to the invention therefore enables, in particular, a safe, in particular contamination-free, transport of the electrical rodenmaterials to a location where a next production step is carried out, so that there is no need for vacuum drying of the electrode material again, if necessary, after it has been removed from the container at this location, with the result that energy costs can be saved.
  • the container according to the invention creates a safe, simple, sustainable and cost-optimized transport and storage option.
  • an overpressure can be formed in the transport space relative to the environment by means of the supply device.
  • the overpressure can be built up in the transport space and then maintained, which does not require a continuous or permanent supply of the transport space with the gas.
  • the gas supply can be switched off after a desired overpressure has been reached.
  • a dry room atmosphere preferably with a dew point of ⁇ 20° C., can advantageously be formed in the transport room by means of the supply device.
  • the dew point can also be ⁇ -30 °C, ⁇ -40 °C, ⁇ -50 °C or ⁇ -60 °C.
  • the gas can have this dew point.
  • the transport space can then be permanently supplied with the gas, for example in an air recirculation mode. Residual moisture is then very low, so that the electrode material is well protected.
  • the gas can advantageously be an inert gas or inert gas, in particular nitrogen, carbon dioxide or an inert gas, for example argon.
  • the gas can be a gas mixture which has at least two of the aforementioned inert gases.
  • the gas or protective gas can be nitrogen.
  • the nitrogen may be high purity nitrogen having a purity of 99.999%.
  • the container can include the supply device. The container can then be operated autonomously.
  • the supply device can be arranged, for example, on an outer wall of the container or in the transport space.
  • the supply device can be in the form of an external supply device, ie a separate supply device or one that is designed separately from the container.
  • the external supply device can be designed as a central supply device, for example a warehouse, production hall or a transport vehicle, and be set up to supply a plurality of containers or their transport spaces with the gas.
  • the central supply device can then have a central supply line to which the containers can be connected. It is also conceivable that the container has its own supply device and can also be connected to an external or central supply device.
  • the container can have at least one pressure container, in particular a gas cylinder, for storing the gas or a reservoir for compressed gas.
  • the pressure vessel can have a valve or shut-off valve for controlling a gas supply.
  • the pressure vessel can form the supply device.
  • the container can advantageously have a line that can be connected or is connected to the supply device or the pressure container and is connected to the transport space, such that the gas or the gas stored in the pressure container can be supplied to the transport space via the line.
  • the container can have a valve or shut-off valve, preferably a manually operated one, which can be integrated into the line to switch the gas supply on or off. An outflow of the gas can thus be avoided during a loading or unloading process by switching off the gas supply. Only after the container has been sealed gas-tight can the gas supply be switched on and a pressure or excess pressure built up in the transport space.
  • the container can have a filter device for cleaning the gas or air, which can be integrated into the line.
  • An atmosphere with a desired cleanliness class can then also be formed in the transport space.
  • the container can advantageously have a pressure valve.
  • a pressure-limiting valve and/or a pressure-reducing valve can be provided as the pressure valve. In this way, an overpressure can be generated and maintained in the transport space.
  • the supply device can be designed as an air recirculation unit.
  • the transport space can then be continuously supplied with the gas.
  • the container can in particular have an inlet air inlet and an outlet air outlet.
