Definitions

  • Such round cells are typically provided with a wound-up electrode coil as the active material.
  • a construction with prismatic cells is possible, which better exploit the typically available installation space, since cavities do not remain between the battery individual cells, as in the case of round cells. With such prismatic cells can thus be realized even higher power volume.
  • a typical structure for such prismatic cells is described, for example, in the non-prepublished German application DE 10 2007 063 184.9.
  • the structure of this so-called Frame flat cell provides that a frame made of an insulating material together with two cladding forms the housing of the battery single cell. Inside the frame, the active material array is then typically arranged as a stack of electrode foils.
  • closed surface or at least after a short distance piece within the closed at least one filling body pores formed so that no / only little electrolyte penetrates into the packing.
  • it has a certain elasticity, which allows the above advantages.
  • packing of closed-cell foam is a very light component, so that hardly any additional mass is introduced into the structure of the single battery cell by the filling body.
  • Sheaths has.
  • the at least one filling body is arranged in the region of the connection of the arrangement with the enveloping sheet, which does not lie in the region of this step.
  • This structure allows the two typically resulting Cavities in the area in which the electrode stack connected to the respective cover plate, for example, welded, is to fill up accordingly. Due to the step-shaped design of the frame on the one hand and the insertion of a filling body on the other hand can be achieved that with simple and efficient means all larger cavities are filled with corresponding packing or the material of the frame itself.
  • the structure as described here has the advantage that the frame can be sprayed onto one of the cladding sheets. There are no
