storage battery

Abstract

The invention relates to an accumulator (1) having an at least partially electrically conductive housing (2) and primary cells (3) arranged in the housing (2). In order to provide an improved and reliable solution for reducing harmful overvoltages in the housing (2) of an accumulator (1), the invention provides that between the housing (2) and the primary cells (3) at least partially At least one non-conductive, heat-resistant and air-permeable textile (4) is provided.

Description

technical field

[0001] The invention relates to an accumulator having an at least partially electrically conductive housing and primary cells arranged in the housing. Background technique

[0002] Batteries are used today in different fields. For example, the mobile use of accumulators in electrically driven motor vehicles, in particular electric vehicles, plug-in hybrid vehicles and hybrid motor vehicles, is known for supplying the electric drive of the motor vehicle with electrical energy from the accumulator. Furthermore, the mobile use of accumulators in the field of electrical consumers, such as notebook computers, mobile telephones, etc., is known. Furthermore, batteries are also used stationary, for example in wind power installations. These non-exhaustive applications place very high demands on the battery with regard to its reliability, efficiency and lifetime.

[0003] The accumulator has a housing in which a primary cell is arranged, which comprises electrochem...

Embodiment Construction

[0023] figure 1 A partial schematic view of an exemplary embodiment of an accumulator 1 according to the invention is shown. The accumulator 1 comprises an electrically conductive housing 2 and a primary cell 3 arranged in the housing 2 . A non-conductive, heat-resistant and air-permeable textile 4 is arranged between the housing 2 and the galvanic cells 3 . The textile 4 is formed by a nonwoven, the nonwoven consisting of aramid. A metal foil 5 is arranged between the galvanic cell 3 and the textile 4 . A non-conductive layer 6 or 7 is respectively arranged both between the metal foil 5 and the textile 4 and between the metal foil 5 and the galvanic cell 3 . The housing 2 comprises a receptacle 8 for receiving the galvanic cells 3 and a cover 9 closing the receptacle 8 , on which a connecting terminal 10 of the accumulator 1 and a vent valve, not shown in detail, are arranged.
