A battery cell () comprising at least one electrode unit () having an anode (), a cathode () and a separator () which is arranged between the anode () and the cathode (). In this case, the separator () has an electrically conductive core layer () and at least one ionically permeable edge layer (). The invention also relates to a method for controlling ion flow within the battery cell (), wherein an electrical connection is established between the electrically conductive core layer () of the separator () and a current collector () of the anode () or a current collector () of the cathode ().

Battery cell and method for controlling ion flow within the battery cell

A method for operating a secondary battery which comprises multiple interconnected, bridgeable battery subunits and is situated in a compartment of an electrically driven vehicle, in particular a watercraft, includes detecting an accessibility of each battery subunit, and activating the battery subunits in accordance with the accessibility of the particular battery subunits.

Method for operating a rechargeable battery

A short-circuit protection device for limiting a battery current of a battery strand having at least one battery cell and for guiding an output current to a consumer network via a first network terminal and a second network terminal connected to the short-circuit protection device, the short-circuit protection device compring: a first switching element configured to interrupt the battery current to limit the output current; at least one current detection means; a comparison arrangement configured to compare the output current with a predefined target value; at least one inductor arranged series with the switching element; an inductor current regulation arrangement configured to actuate the switching element; and a first bridge device configured to bridge at least one battery cell of the battery strand and limit the predefined target value to a predefined maximum value of a short-circuit current.
