NOVELTY - The cell housing (10) made of non-ceramic material, comprises an electrically insulating layer (14) which is made from a ceramic material. The electrically insulating layer is arranged on the inside/outside of cell housing. The electrically insulating layer (14) is structured by a wave profile, in particular two-dimensional wave profile, and a triangular profile or a rectangular profile. The ceramic material is selected from the group consisting of enamel or polymer-ceramic composite.    USE - Cell housing for partially enclosing cell space of battery e.g. lithium battery of battery system (claimed) mounted in vehicle.    ADVANTAGE - The cell housing can serve to cause durable and stable electrical isolation of the cell case, compared with other components of battery system. The cell housing with high stability or durability and a secure safety work of vehicle equipped with such a cell housing battery system can be achieved. The cell housing can partially enclose, or completely enclose the cell space and so separated from the external environment. The cell housing or basic structure has a good stability against external influences, and the cell space components can be reliably protected. The cell housing or basic structure is very inexpensive to produce. The electric isolation of the casing is provided, in order to avoid thermal runaway or other damage or malfunction of the battery or the battery system, by contact of the cell case with other adjacently arranged cell housings or other components of battery system. The protection of cell space arranged in the component, from leakage of the cell space is improved. The ceramic materials are not only stable against chemically or electrochemically active substances, but can withstand any problems due to the high thermal stability even high temperatures. The cell portion on outer side can be configured so that no structural changes of battery system or compound of different cells of battery system is necessary. The electrical isolation of the cell housing is made in a cost-effective way.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for battery system.
