Abstract
The present invention relates to a new sandwich cathode design having two cathode active materials provided on opposite sides of a current collector. The respective active materials are similar in terms of, for example, their rate capability, their energy density, or some other parameter. However, one material may have an advantage over the other in one characteristic, but is disadvantageous in another. The cathode is built in a sandwich configuration having a first one of the active materials sandwiched between two current collectors. Then, the second active material is provided in contact with at least the other side of one of the current collectors, and preferably facing the anode. An exemplary cathode has the following configuration: MnO /current collector/SVO/current collector/MnO .
