DETAILED DESCRIPTION
[0011] In the present document, the word "exemplary" is used herein to mean "serving as an example, instance, or illustration". Any embodiment or implementation of the present subject matter described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
[0012] While the disclosure is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawing and will be described in detail below. It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternatives falling within the scope of the disclosure.
[0013] The terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion so that a setup, device or method that comprises a list of components or steps does not include only those components or steps but may include other components or steps not expressly listed or inherent to such setup or device or method. In other words, one or more elements in a system or apparatus preceded by "comprises" or "comprise' does not or do not, without more constraints, preclude the existence of other elements or additional elements in the system or method.
[0014] In the following detailed description of the embodiment of the disclosure, reference is made to the accompanying drawing that forms part hereof, and in which is shown by way of illustration a specific embodiment in which the disclosure may be practiced. This embodiment is described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.
[0015] The only Fig. shows in a schematic sectional view a battery 10 for a vehicle. Thus, the vehicle comprises the battery 10. For example, the vehicle also comprises at least one electric machine configured to drive the vehicle. In order to drive the vehicle by the electric machine, the electric machine is supplied with electrical energy stored in the battery 10. Thus, for example, the vehicle is configured as an electric vehicle such as a battery electric vehicle (BEV). The battery 10 comprises a housing 12 which is also referred to as a battery housing. Moreover, the battery 10 comprises a plurality of battery cells 14 which are also referred to as cells. The battery cells 14 are electrically connected with each other. In the battery cells 14, said electrical energy is stored.
[0016] As shown in the Fig., the respective battery cells 14 comprise at least or exactly one cathode 16 being a first electrode of the respective battery cells 14. For example, the respective battery cell 14 further comprises or exactly one anode being a second electrode of the respective battery cell 14. The anodes are not shown in the Fig. For example, the battery cells 14 are electrically connected with each other via their electrodes. Moreover, the battery cells 14 may be configured to provide the electrical energy stored in the battery cells 14 via said electrodes.
[0017] The respective cathode 16 is made of a cathode material blend. This means, that the cathode material blend is a mixed cathode material or a mixed cathode active material. The cathode material blend comprises a phosphate cathode material being a lithium manganese iron phosphate (LMFP) material having a weight percentage in a range of 1 to 20 weight percent. Moreover, the cathode material blend comprises a high nickel content oxide material being lithium nickel manganese cobalt oxide (NMC) or lithium nickel cobalt aluminum oxide (NCA). Said high nickel content oxide material is also referred to as a high nickel content oxide cathode material. Preferably, the high nickel content oxide material has a weight percentage in a range of 70 to 99 weight percent.
Moreover, preferably, said high nickel content oxide material is NMC811 or has a greater nickel content than NMC811.
[0018] High nickel content oxide materials such as, for example, NMC811 or NCA are not very stable when de-lithiated to a certain extent. This may lead to cycle life issues as well as other effects. Further, especially at high lithiafion states (battery at low state of charge) high nickel content oxides usually show elevated impedance. Nickel and cobalt cost more than iron or manganese, so blending can also reduce cost for the same or better performance, depending on the battery specifications.
[0019] Phosphate cathode materials have been used to improve NMC type oxide cathode materials before but all that was found had lower nickel content, for example 60 percent, so previous materials do not include advantageous synergistic effects discovered in said cathode material blend. It was found that rate capability may be improved with blending. This seems counter intuitive because, usually, LMFP used as phosphate does not have good conductivity. LMFP particles however are designed to compensate for the low ionic conductivity by the use of a smaller particle size and often by adding carbon coating for better electronic conductivity. Cathode utilization was improved for high rate discharging (90 percent both NMCs, 10 percent LMFP) and fast charging was improved (98 percent NMC-B, 2 percent LMFP-A). Therefore, the material combinations used in the invention comprise synergistic effects as compared to previous solutions.
[0020] Thus, for manufacturing said cathode material blend 1 weight percent to 20 weight percent of said phosphate cathode material is blended into said high nickel content oxide material, in particular following specific processing conditions, wherein said blending will not decrease the energy density at low rates significantly but will improve high rate discharging utilization of the cathode, sometimes fast charging utilization, cycle life and stability at high temperature. Blending does not have the same effect for every cathode material source. Using oxide and phosphate materials form different sources leads to different benefits. Particle size, structure and surface engineering may influence where to find the synergies.
[0021] LMFP offers high safety, but lower energy density. Lower energy density makes LMFP materials less desirable as the primary cathode for automotive applications. However, addition of smaller, potentially carbon-coated particles of LMFP, with shorter ion travel distances and improved electronic conductivity can be beneficial. These materials are generally cheaper than NMC materials. For example, at least the following advantages may be realized by said cathode material blend: better high rate material utilization (cost lower, depending on battery specifications), better cycle life (cost), lower overall material cost, and safety benefits (lower battery system cost).
