Machines And Apparatus With Individual Functions - System For Winding Pouch Cells. The Center For Solar Energy And Hydrogen Research Baden-W rttemberg (Zsw) Is Active In The Fields Of Generating And Storing Renewable Energies Since 1988. The Electrochemical Energy Technologies Division Is Currently Conducting Research 120 Employees Have Been Developing Battery Systems With A Focus On Lithium-Ions For More Than 25 Years Up To Future Systems (Post-Lithium). The Zsw Forms The Entire Value Chain From Material, Electrode And Cell Development To Production Research. The Starting Material Is Electrodes Coated On One Or Both Sides (Anode And Cathode For Li-Ion Batteries). The Individual Electrodes Are Made Of Coated Copper Or Aluminum Foils Made. The Tendered System Should Consist Of One Magazine, With Different Compartments For Anodes And Cathodes, Remove The Electrodes And Stack Them Alternately According To The Given Recipe. Located In Between There Is A Separator For The Electrical Isolation Of The Cathode And Anode. The Separator Is Unwound From An Endless Roll (Not A Single Sheet). At The End Of The Batch Process A Specified Number Of Further Windings Should Be Completed. At The End Of During The Winding Process, The Separator Is Automatically Cut Off And Secured With A Kapton Tape Fixed So That A Stable Wrap Is Created That Can Be Used In The Further Work Steps Cannot Resolve Itself. The Wrap Is Automatically Placed In A Magazine Or A Box Placed. The System Must Be Able To Automatically Process Up To Ten Wraps To Produce Independently. The Following Arrangements Of The Batch Process Are Carried Out: Cathode Anode Cathode Anode Cathode Anode Structure Of Coil: One Coil Consists Of At Least One Anode And One Cathode. A Wrap Can Consist Of Up To Max. 61 Layers, I.E. Up To 30 Anodes And 31 Cathodes, Or 31 Anodes And 30 Cathodes - Depending On Whether The Last Electrode Is An Anode Or Is A Cathode. For Further Specifications See Specifications.
