An energy storage unit, such as a galvanic cell, is composed of a first electrode (10), a second electrode (18) and a separation element (24), which is arranged between the first and the second electrode. Therein, the first and the second electrode (10, 18), respectively, comprise an electrode collector (12, 20) and an active electrode material (14, 22), which is applied onto the respective electrode collector on one side or on both sides. In order to improve the longterm stability, in particular for large format lithium-ion cells, the electrode collector (12, 20) of the first and/or the second electrode (10, 18) is made of a copper material, which is technical-grade oxygen-free having at least approximately 99.9% by weight copper and a specific phosphorous content. |
