NOVELTY - The battery module (1) has two battery cells (3) and a module housing (5). The battery cells are arranged in the module housing. An insulating oil-soaked paper material (7) is provided between the battery cells and the module housing. The oil-soaked paper material is provided between the individual battery cells. The oil-soaked paper material comprises aramid fibers. The oil is transformer oil or is electrically insulating.    USE - Battery module used in hybrid vehicle, electric vehicle and building in connection with solar cell.    ADVANTAGE - The battery module is manufactured inexpensively and with less labor-intensive. The battery cells are separated spatially and electrically by the oil-soaked paper material from the electrical conductive module housing. The costs can be saved by the use of oil-soaked paper material in relation to lacquer finish process. The labor can be reduced compared to use of film and the manufacture of the battery module is simplified. The electrical insulation is offered with the help of oil-soaked paper material so that high breaking and/or chafing through strength are achieved compared to use of film. The oil can prevent moisture absorption of the paper material. The oil is executed to reduce inflammableness of the paper material and to increase the safety of the battery module. The oil contributes to increase the dielectric strength of paper material and probability to reduce arcing. The better flexibility and workability of the oil-soaked paper material are achieved. The use of aramid fibers in the paper material ensures a very high strength. The resistance of the paper material against acids and alkalis is increased by aramid fibers.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for manufacturing battery module.    DESCRIPTION OF DRAWING(S) - The drawings show the cross-sectional view of the battery module.
