Embodiment Construction
[0065] exist figure 1 A lithium-ion battery 11 (hereinafter also simply referred to as battery 11 ) is shown in . The accumulator has a negative pole M and a positive pole P, which assume the function of current collectors. The positive pole P and the negative pole M are respectively provided with contacts 12, so that the positive pole and the negative pole can be contacted to the outside for discharging and charging. Furthermore, the accumulator is cast in a housing 13 which protects the accumulator 11 and is electrically insulated from the outside.
[0066]The structure of the battery 11 is as follows. The anodes A and the cathodes K are each produced as a stack 14 , wherein the anodes A and the cathodes K alternate with each other and are each separated by an electrolyte E. Also provided in the electrolyte E is a separator S which ensures the function of the accumulator 11 in that it only allows the passage of lithium ions.
[0067] The stack 14 is layered such that the...

Abstract
The invention relates to a lithium-ion battery (11) having an electrolyte (E), in which a cathode (K) and an anode (A) separated from the cathode by a separator are arranged. The invention also relates to a method for producing such a battery (11). In the storage battery, a first current collector is provided at an anode as a negative electrode (M) of the storage battery, and a second current collector is provided at a cathode as a positive electrode (P) of the storage battery. The storage battery has a sandwich structure, and the outermost layer of the storage battery is composed of a negative electrode (M) and a positive electrode (P). According to the invention, the anode and the cathode are arranged laterally next to each other between the anode and the cathode. In other words, the arrangement is oriented perpendicular to an interlayer formed by the positive electrode and the negative electrode. The anode and the cathode are separated from each other by an electrolyte and a separator. As a result, it is possible to advantageously form an arrangement structure that can also achieve high capacitance and battery power density. Current can flow through the end sides of the anode and the cathode, respectively, thereby ensuring a higher power density.
