Definitions

  • Pouch cells have a flexible housing made of an aluminum-plastic composite film.
  • Round cells have a cylindrical metal housing and prismatic cells have a prismatic metal housing.
  • battery cell production can be divided into the following areas: electrode production, cell assembly (assembly of the cell) and cell conditioning.
  • electrode production cell assembly (assembly of the cell)
  • cell conditioning cell conditioning.
  • the production of electrodes hardly differs in terms of cell formats.
  • the cell assembly and cell conditioning show clear differences.
  • lithium-ion battery cells go through the cell conditioning steps (synonyms: cell finishing, formation).
  • the actual formation is only one sub-step in cell conditioning.
  • “formation” is often used as a synonym for all steps.
  • the exact sequence of the process sequence depends on the cell manufacturer. A possible reference sequence is shown below:
  • Process step Pre-Aging: Process step in which the battery cell is stored in a chamber at room temperature or at an elevated temperature (approx. 45 ° C) for up to 24 hours. The aim of the process step is the homogeneous distribution of the electrolyte inside the cell.
  • the battery cell is located in a product carrier (usually without a clamping device).
  • Process step Formation (initial charge and discharge): Process step in which the battery cell is charged and discharged for the first time at room temperature or at an elevated temperature (approx. 45 ° C). Depending on the cell manufacturer, the battery cell is charged different times and at different speeds.
  • the battery cells are located in a product carrier.
  • the product carrier In the case of pouch cells, the product carrier has a clamping device in order to exert a defined pressure on the cells (pouch cells do not have a rigid housing, which is why the anodes and cathodes in the cell can move away from each other. This is prevented by pressing).
  • 3rd process step degassing the cell. During the first charging and discharging processes, decomposition products are formed by the electrolyte. These collect in gaseous form in the cell. In the case of prismatic cells and pouch cells, these gases must be "vented”.
  • Process step Aging: Process step in which the battery cell is stored in a chamber at room temperature or at an elevated temperature (approx. 45 ° C) for up to 21 days.
  • the battery cell is located in a product carrier (usually without a clamping device).
  • the battery cells can be located in product carriers and can be moved from one process step to the next. It is also known that the product carriers can exert pressure on pouch cells.
  • the process section of cell conditioning is considered to be time-consuming, cost-intensive and inflexible in terms of cell geometries and formats. This is due in particular to the fact that each battery cell format requires specifically adapted system technology.
  • the battery cells have to be electrically contacted in a complex manner within the system, since, depending on the respective battery cell, the connections are arranged at different spatial positions and the connections themselves may also have different geometries.
