Abstract
A battery includes a housing in which at least one battery cell and a device configured to dry air present in a housing inner chamber are arranged. The battery also includes a molded body made of a porous, moisture-absorbing material that is arranged such that it extends both into the housing inner chamber and into an outer chamber of the housing and connects said chambers to each other such that moisture is conducted there between. The part of the molded body present in the housing inner chamber is connected to the device configured to dry the air present in the housing inner chamber such that collected water is transferred out of the device to the molded body for air drying.
