LITHIUM ION CELL HAVING IMPROVED AGING BEHAVIOR

摘要

The invention relates to a molded secondary galvanic cell, comprising at least one positive electrode containing a metal compound which is able to reversibly incorporate and release lithium in the form of ions; at least one negative electrode containing a carbon compound which is able to reversibly incorporate and release lithium in the form of ions, and/or a metal and/or semimetal that can be alloyed with lithium; an electrolyte by means of which lithium ions can wander back and forth between the at least one positive and the at least one negative electrode; and mobile lithium available for incorporation and releasing processes in the electrodes; wherein the capacity of the at least one negative electrode for receiving lithium is greater than that of the at least one positive electrode, the at least one negative electrode comprises a higher capacity than that which is necessary for receiving the entire amount of mobile lithium present in the cell, and the mobile lithium is present in the cell in a quantity which exceeds the capacity of the at least one positive electrode for receiving lithium. The invention further relates to a battery having at least one such cell, and to a method for producing such a battery.
