Method for insulating a battery module

A method for insulating a battery module (100) which has a multiplicity of battery cells (10), having at least one foldable insulation element (20), the method comprising at least the following steps:

• a) forming from the insulation element (20) a first receptacle pocket (21) for receiving at least one battery cell (10),
• b) closing the first receptacle pocket (21) by means of attachment sections (22) which are arranged laterally on the insulation element (20), as a result of which the battery cell (10) is surrounded at least on five sides by the insulation element (20), as a result of which the individual battery cell (10) is insulated with respect to an adjacent battery cell (10),
• c) forming from the insulation element a second receptacle pocket for receiving the adjacent battery cell, the second receptacle pocket formed from the same insulation element as the first receptacle pocket, the second receptacle pocket formed adjacent to and seamlessly connected to the first receptacle pocket via the insulation element, and
• d) closing the second receptacle pocket (21) by means of second attachment sections (22) which are arranged laterally on the insulation element (20) such that the adjacent battery cell (10) is surrounded at least on five sides by the insulation element (20) and is insulated with respect to an adjacent battery cell (10).
