ENERGY STORAGE CELL AND ENERGY STORAGE SYSTEM

摘要

The invention relates to an energy storage cell (3), comprising a housing (2), an electrolyte (9) present in the housing (2), and two electrodes (4, 5), each of which is disposed at least partially in the housing (2) and at least some of which are in contact with the electrolyte (9). The energy storage cell (3) is characterized in that at least one of the electrodes (5) comprises a first section (5A), which is not in contact with the electrolyte (9), and a second section (5B), which is in contact with the electrolyte (9), wherein the first section (5A) is made at least partially of aluminum or an aluminum alloy and the second section (5B) is made of a material that is different from aluminum. In this way, the weight and the costs can be reduced.
