[0075] In the accompanying drawings, reference numerals may be used repeatedly to identify similar and / or identical elements. Detailed Implementation

[0076] Although the battery pack system described in this article is for vehicle applications, it can also be used for non-vehicle applications.

[0077] Now for reference Figure 1 The vehicle 10 includes a battery pack 20, which comprises one or more pouch-type bipolar solid-state battery modules. In some instances, the battery pack 20 may be used in low-voltage automotive battery pack systems, such as 12V battery pack systems for starting the vehicle, supporting stop / start functions, and / or powering vehicle accessory loads or other vehicle systems. In other instances, the battery pack 20 may be used for other purposes, such as propulsion.

[0078] Now for reference Figure 2 An example of parallel-connected bipolar solid-state battery cell 100 is shown. In this example, the parallel-connected bipolar solid-state battery cell 100 includes a cathode electrode 112, a spacer 114, and an anode electrode 116 arranged in the stack and connected in parallel as shown. Figure 2 In this example, the fuel cell stack includes a cathode current collector 118, a cathode electrode 112, a spacer 114, an anode electrode 116, an anode current collector 120, and the spacer 114. The external tab 122 connected to the cathode current collector 118 is connected to the positive terminal "+". The external tab 124 connected to the anode current collector 120 is connected to the negative terminal "-".

[0079] Now for reference Figure 3The diagram illustrates M bipolar solid-state battery cells 100-1, 100-2, ..., 100-M arranged in series within a battery pack housing 200, where M is an integer greater than 1. In this example, M = 4. The battery pack housing 200 includes a lower portion 204 and a cover 206. In some examples, the lower portion of the battery pack housing 200 has a rectangular cross-section. The lower portion 204 includes a bottom surface, first and second sidewalls, and first and second endwalls. Coatings or bipolar plates 210-1, 210-2, and 210-3 are arranged between the first and second sidewalls (adjacent bipolar battery cells). The outermost adjacent bipolar battery cells are arranged between the positive terminal 214 and one of the coatings, and between the negative terminal 216 and one of the coatings, respectively.

[0080] In some examples, cladding plates 210-1, 210-2, and 210-3 are received in channels 213 formed on one or more inner surfaces of the lower portion 204 and the cover 206 of the battery pack housing 200. In this example, bipolar battery pack cell 110-1 is arranged between the positive terminal 214 and cladding plate 210-1. Bipolar battery pack cell 110-2 is arranged between cladding plates 210-1 and 210-2. Bipolar battery pack cell 110-3 is arranged between cladding plates 210-2 and 210-3. Bipolar battery pack cell 110-4 is arranged between cladding plate 210-3 and the negative terminal 216.

[0081] Battery pack cells are typically compressed during manufacturing. (Use) Figure 3 When the battery pack has a rigid casing, the pressure between the cells is insufficient. Low compression reduces cold-start capability.

An outer lamination 230 is arranged adjacent to the outermost battery cells of the M parallel-connected battery cells 226-1, 226-2, ..., and 226-M. A bipolar lamination 240 is arranged between adjacent battery cells of the M parallel-connected battery cells 226-1, 226-2, ..., and 226-M.

[0084] Now for reference Figure 6 The assembled pouch cell module is shown. An outer lamination 230 encapsulates the M parallel-connected battery cells 226-1, 226-2, ..., 226-M with external tabs 122C and 124A extending from opposite ends for connection. The flexible housing allows sufficient pressure to be generated between the battery cells. Higher compression enables cold-start capability.

The bipolar laminate 240 includes a cast polymer layer 310, an adhesive layer 314, a bipolar metal layer 316 (including a first metal layer 318 and a second metal layer 322), an adhesive layer 326, and a cast polymer layer 330. Cast polymer layers 310 and 330 are coated at the edges of the bipolar laminate 240. The metal layer portions between the edges allow adjacent battery cells of the M parallel-connected battery cells to be connected in series. Cast polymer layers 310 and 330 tightly seal each battery cell after hot pressing and prevent electrolyte leakage into adjacent battery cells.

[0086] In some examples, the first metal layer 318 is made of aluminum, and the second metal layer 322 is made of copper. In some examples, the metal layers are made of foil or clad foil. In other examples, the first metal layer 318 and the second metal layer 322 are made of a material selected from stainless steel, nickel, titanium, nickel-copper cladding, aluminum-nickel cladding, aluminum-stainless steel cladding, nickel-stainless steel cladding, and / or other metals or alloys.

[0087] In some examples, the cast polymer layers 310 and 330 have a thickness of 1 to 50 μm. In some examples, the adhesive layers 314 and 326 have a thickness of 1 to 20 μm. In some examples, the first metal layer 318 and the second metal layer 322 of the bipolar metal layer 316 have a thickness of 2 to 50 μm.

The outer lamination 230 includes an outer layer 340, an adhesive layer 344, a metal layer 348, an adhesive layer 352, and a cast polymer layer 356. In some examples, the outer layer 340 is selected from nylon, PE, and oriented nylon film. In some examples, the outer layer 340 has a thickness of 1 to 80 μm. In some examples, the metal layer 348 is selected from aluminum, stainless steel, and titanium. In some examples, the metal layer 348 has a thickness of 2 to 60 μm. In some examples, the cast polymer layer 356 is made of a material selected from polypropylene (PP), polyethylene (PE), or other polyolefin layers. In some examples, adhesive layers 344 and 352 comprise polyester polyurethane and have a thickness of 1 to 10 μm.

[0089] A bipolar metal layer enables the battery cells to be connected in series. A cast polymer layer is coated on the edges of the bipolar metal layer to prevent electrolyte leakage into adjacent cells and ion short circuits. An outer lamination encapsulates the assembly in a pouch and prevents unwanted electrolyte leakage or gas exchange. During operation, the battery cells can... Figure 6 The diagram shows high compression pressure to enhance the performance of the pouch cell module.

[0090] Now for reference Figure 9 and 10 An example of a method for manufacturing a pouch cell battery pack module is shown. Figure 9 At point 410, M parallel-connected battery cells are fabricated. At point 414, the anode and cathode tabs of the M parallel-connected battery cells are welded. At point 418, a liquid or gel precursor is optionally injected (allowing gel curing) for liquid or semi-solid applications. At point 422, the M parallel-connected battery cells, bipolar laminate, and outer laminate are stacked. At point 426, the edges of the pouch-type battery module are sealed.

At position 464, the anode and cathode tabs of the M parallel-connected battery cells are welded. At position 468, the M parallel-connected battery cells, bipolar laminate, and outer laminate are stacked. At position 472, three of the four edges of the pouch-type battery module are sealed. At position 476, a liquid or gel precursor is optionally injected (and gel curing is allowed) for liquid or semi-solid applications. At position 480, the remaining edges of the pouch-type battery module are sealed.

[0092] Now for reference Figure 11 An exploded view of an example of a pouch cell module 500 is shown. M battery cells 226-1, 226-2, ..., and 226-M are provided in parallel connection. An outer lamination 230 is arranged adjacent to the outermost battery cells of the M parallel-connected battery cells 226-1, 226-2, ..., and 226-M. A first lamination 524 and a second lamination 528 are arranged between adjacent battery cells in the M parallel-connected battery cells 226-1, 226-2, ..., and 226-M.

[0093] Now for reference Figure 12 The diagram shows a first lamination film 524 and a second lamination film 528.
