VOLTAIC ELEMENT

摘要

The invention relates to a voltaic element comprising at least one lithium intercalating electrode and a housing which consists of a flexible film material and through which diverters that are connected to the positive and negative electrodes of the element are conducted to the exterior, said diverters being optionally connected to an electronic safety system. According to the invention, at least one of the diverters that connect the element to the electronic safety system, for example the diverter that is connected to the collector of the negative electrode and is conducted to the exterior, consists of nickel-coated copper foil. The copper foil is preferably nickel-plated. An additional protective element, in particular a PTC resistor or a thermal fuse, is optionally integrated into the connection between the element and the electronic safety system.
