Definitions
- the present invention relates to an electrode for an energy store and an energy store with such an electrode.
- Energy storage is increasingly used in electric vehicles and electric hybrid vehicles, which is why there is an increasing demand for energy storage with a large capacity, high performance and long-term stability.
- the lithium (ion) cells occupy a special position, especially as secondary cells, due to their high specific energy storage density.
- the energy accumulator embodied here as a lithium-ion cell contains in each case a first electrode, a second electrode and a separating element between the first and the second electrode or an alternately stacked arrangement of these components.
- the electrodes are usually formed from an electrode carrier to which an active electrode material is applied on one or both sides.
- the anode is often formed of an anode support made of copper and an anode active material such as graphite, and the cathode is commonly formed of an aluminum cathode support and a lithiated oxide cathode active material.
- the present invention has for its object to provide an energy storage device with improved long-term stability or an electrode for such energy storage.
- an electrode for an energy store with the features of claim 1.
- Advantageous embodiments and further developments of the invention are subject matter of the dependent claims 2 to 6.
- the electrode for an energy store contains an electrode carrier and an active electrode material which is applied to the electrode carrier on one or both sides.
- the electrode carrier is formed from a technically oxygen-free copper material with at least about 99.9 wt .-% copper and a phosphorus content.
- the material for the electrode carrier is essentially a phosphorus-deoxidized copper.
- the phosphorus oxide particles in the copper material formed by the phosphorus content nucleate during solidification and produce a fine-grained and homogeneous crystal structure.
- This fine-grained structure leads to a more uniform application of current across the surface of the electrode carrier and thus reduces the risk of destruction of the crystal structure. In other words, the long-term stability of the electrode is significantly increased.
- the electrical conductivity of such a copper material is comparable to that of a conventionally used copper material, which consists essentially of a technically oxygen-free copper without deoxidizer.
- the electrode configured as described above is therefore particularly suitable for large-sized energy storage devices with a large capacity and high performance, such as those required for electric vehicles and hybrid electric vehicles.
- the copper material of the electrode carrier contains at least about 99.95 wt% copper.
- the phosphorus content of the copper material of the electrode carrier is preferably in a range of about 0.001 to about 0.10 wt%, more preferably in a range of about 0.002 to about 0.007 wt%. According to a second aspect, the above-mentioned object is achieved by an energy store having the features of claim 7. Advantageous refinements and developments of the invention are the subject of the dependent claims 8 to 14.
- the energy storage device includes a first electrode (e.g., negative electrode, anode), a second electrode (e.g., positive electrode, cathode), and a separator between the first and second electrodes that prevents direct electrical contact between the two electrodes.
- a first electrode e.g., negative electrode, anode
- a second electrode e.g., positive electrode, cathode
- the first and / or the second electrode are formed as an electrode as described above.
- the long-term stability of the electrode can be improved by an electrode configured according to the invention, which of course also significantly improves the long-term stability of the entire energy store.
- the energy store may be, for example, a secondary cell (i.e., rechargeable galvanic cell), a primary cell (i.e., non-rechargeable galvanic cell), a capacitor, or the like. Particularly preferred is the use of the electrode according to the invention in a lithium (ion) cell.
- the energy store may comprise a stack of a plurality of first electrodes and a plurality of second electrodes, which are alternately stacked and between each of which a separating element is arranged.
- the present invention is advantageously applicable both to energy storage devices in which the first electrode (s) and the second electrode (s) are layered, as well as to those in which the first (n) and the second (n) layers are layered. Electrode (s) are wound.

- the electrode 10 has an electrode carrier 12 to which an active electrode material 14 is applied on both sides.
- the active electrode material 14 is not applied to the electrode carrier 12 in the entire region, so that the electrode carrier 12 protrudes from the active electrode material 14 on at least one side.
- This protruding from the active electrode material 14 portion of the electrode carrier 12 can be used as a current collector 16 for supplying a charging current to the electrode 10 and discharging a discharge current from the electrode 10 so.
- the illustrated in Fig. 2 embodiment differs from the above first embodiment in that the active electrode material 14 is applied on both sides of the entire surface of the electrode carrier 12 so that it is not out of the protrudes active electrode material 14.
- a separate current conductor can be connected to the electrode carrier 12 in its extension (eg, welded).
- the third embodiment of the electrode shown in FIG. 3 differs from the first embodiment described above in that the electrode carrier 12 is coated on one side only with the active electrode material 14.
- the fourth embodiment of Fig. 4 illustrates a combination of the above second and third embodiments.
- the active electrode material 14 is applied only on one side to the electrode carrier 12 and the electrode carrier 12 is provided on the one side substantially over the entire surface with the active electrode material 14.
- the electrode carrier 12 is provided in all embodiments, for example in the form of a film, a tape, a plate, a sheet or the like and deposited electrolytically on rollers, for example, from a corresponding solution.

- a first electrode 10 eg negative electrode or anode
- a second electrode 18 eg positive electrode or cathode
- separator 24 between the two Electrodes 10, 18.
- the first electrode 10 for example, an electrode as shown in Figs. 1 to 4 is used.
- the second electrode 18 is basically constructed analogously to the first electrode 10, i. it also contains an electrode carrier 20 and an active electrode material 22 which is applied to the electrode carrier 20 on one or both sides.
- the separating element 24 between the two electrodes 10, 18 prevents direct, electrically conductive contact between the two electrodes 10, 18.
- the separating element 24 can terminate flush with the electrodes 10, 18 (in particular their active regions 14, 22), as indicated in FIG. 5. However, it can also be advantageous if the separating element 24 projects beyond the active electrode material 14, 22 of the directly adjacent electrode 10, 18 on at least one side.

- the copper material of the invention is essentially a phosphorus-deoxidized copper.
- the phosphorus oxide particles formed nucleate upon solidification of the copper material and produce a fine-grained homogeneous crystal structure.
- Such a fine-grained microstructure causes a more uniform current impact across the surface of the electrode carrier 12 and thus prevents destruction of the crystal structure.
- FIGs. 6A and 6B show a comparison of the crystal microstructures between a conventionally used copper material (Fig. 6A) and the copper material used in the present invention (Fig. 6B).

- the production of the electrodes 10, 18 and the energy storage in the invention is not limited to special methods.
- the above-described electrode of the invention is particularly suitable for large-sized energy stores (especially secondary lithium-ion cells) having a large capacity and high performance of over 3 or 5 Ah up to 300 Ah and more, which also has excellent long-term stability of, for example, over 3,000 charge / discharge Cycles and more and require security of supply.
