Lithium accumulator system, especially for use in a standard 14V vehicle electrical system

摘要

The present invention relates to an electrode for a lithium accumulator cell for storing electrical energy in a lithium accumulator (4) which has a certain number of series-connected lithium accumulator cells and for outputting or receiving a voltage within a lower and upper one Voltage limit (22, 24) is provided in an energy supply network (2). The lithium accumulator cell can be connected via the electrode to an output electrode of the lithium accumulator (4) or an electrode of another accumulator cell. The electrode has a material that pushes the voltage range between a minimum open-circuit voltage (36) and a maximum open-circuit voltage (34) of the lithium accumulator between the lower and upper voltage limit (22, 24).
