The flexible battery has a flexible packaging shell to ensure that the flexible battery can be bent or folded during use. In the related art, an aluminum plastic film is used to form the package housing. The inventors have found that the flexibility of the package case in the related art has room for further improvement to optimize the flexibility of the flexible battery.
Based on the foregoing, embodiments of the present disclosure provide a flexible battery. Fig. 1 to 5 are schematic structural views of a flexible battery provided according to various embodiments.
As shown in fig. 1, the flexible battery includes an electrode assembly 10, a package case 20 covering the electrode assembly 10, and an electrode terminal 30 (not shown in the connection part) provided on the package case 20 and connected to the electrode assembly 10.
The package case 20 encapsulates the electrode assembly 10, the electrode terminal 30, and the electrolyte as one body. Wherein the package case 20 forms a package cavity 25, and the electrode assembly 10 and the electrolyte are positioned inside the package cavity 25. The electrode terminal 30 has one end connected to the electrode assembly 10 and the other end located outside the package cavity 25 for cooperation with a power interface of an external assembly.
In one embodiment, as shown in fig. 2, the electrode assembly 10 includes a battery anode 11, a separator 12, and a battery cathode 13, which are stacked.
The battery anode 11 includes an anode current collector and an anode active material layer. Wherein the anode active material layer is provided on at least one face of the anode current collector. Illustratively, an anode active material layer is coated on at least one side of the anode current collector. The battery cathode 13 includes a cathode current collector and a cathode active material. Wherein the cathode active material is disposed on at least one side of the cathode current collector. Illustratively, a cathode active material layer is coated on at least one side of the cathode current collector. Separator 12 is disposed between cell anode 11 and cell cathode 13, separating cell anode 11 from cell cathode 13.
Wherein, the battery anode 11, the battery cathode 13 and the diaphragm 12 are made of flexible materials which can be bent and deformed. Illustratively, the battery anode 11 and the battery cathode 13 are prepared using metal foils, such as copper foil, aluminum foil, cobalt foil, zinc foil, nickel foil, manganese foil, titanium foil, iron foil, silver foil, and the like. The separator 12 is made of a resin film, such as a polypropylene film, a polyethylene film, or the like.
The electrode terminal 30 includes an anode terminal 31 and a cathode terminal 32. Wherein one end of the anode terminal 31 is connected to the battery anode 11 and the other end is exposed to the outside of the package case 20. One end of the cathode terminal 32 is connected to the battery cathode 13, and the other end is exposed to the outside of the package case 20. The portions of the anode terminal 31 and the cathode terminal 32 exposed to the outside of the package case 20 are for cooperation with a power interface of an external device such that the flexible battery supplies power to the external device.
In one embodiment, as shown in fig. 3, electrode assembly 10 further includes an inner casing 14 that encloses battery anode 11, battery cathode 13, separator 12, and electrolyte. The sealability of the flexible battery is further enhanced by the encapsulation of the inner case 14, and the stable use of the flexible battery is ensured. The inner can 14 is made of flexible material and is folded synchronously with the electrode assembly 10 and the outer can 20 when in use.
Optionally, inner housing 14 has a smooth surface that is curved to provide a smooth curve. Or, alternatively, inner housing 14 includes a toughening structure. For example, the toughening structure includes associated recesses and protrusions disposed on the surface of inner housing 14. The toughening structure is wavy for improving the toughness of the inner shell 14.
In one embodiment, as shown in fig. 4, the package housing 20 includes a rubber layer 21, a barrier layer 22, and an adhesive layer 23, which are stacked.
The barrier layer 22 is used to prevent impurities (e.g., moisture, etc.) outside the package case 20 from entering the package cavity 25, and secure the use of the electrode assembly 10. Optionally, the barrier layer 22 is made of a metal foil, which combines both barrier properties and bending properties of the barrier layer 22. Wherein the metal foil is made of aluminum, copper, phosphor bronze, aluminum bronze, copper alloy, etc.
The rubber layer 21 is provided on one side of the barrier layer 22. As an example, the rubber layer 21 is directly attached to the barrier layer 22. For example, the rubber layer 21 is directly formed on the barrier layer 22 by a process of spraying, coating, curtain coating, or the like. As another example, a glue layer 24 is provided between the rubber layer 21 and the barrier layer 22, and the rubber layer 21 is connected to the barrier layer 22 through the glue layer 24.
Alternatively, the thickness of the rubber layer 21 is 20 to 30 micrometers (μm), for example 23 μm, 25 μm, 27 μm, etc.
Illustratively, the rubber layer 21 includes at least one of the following rubber components: nitrile rubber, styrene butadiene rubber, isoprene rubber, neoprene rubber and fluororubber. Of course, the rubber layer 21 may also include other rubber components. Here, when the rubber layer 21 includes a plurality of rubber components, the rubber layer 21 further includes a modifier. The modifier is used for regulating and controlling the combination stability of different rubber components so as to optimize the mechanical properties of the rubber layer 21.
The rubber layer 21 is excellent in flexibility and deformation ability. In the embodiment of the present disclosure, by providing the rubber layer 21 on the barrier layer 22, the flexibility of the entire package housing 20 is optimized, so that the package housing 20 is more easily bent. Accordingly, the flexible battery and the external component are kept synchronously bent, so that the flexible battery is fitted with the external component as much as possible. For example, the degree of deformation of the flexible battery is consistent with the degree of deformation of the flexible display screen, or the degree of deformation of the flexible battery is consistent with the degree of deformation of the wristband.
The rubber layer 21 has elasticity and is not easily broken after being bent a plurality of times. Therefore, when the flexible battery provided by the embodiment of the disclosure is used, the package shell 20 is not easy to damage due to bending, the occurrence of battery fire and other conditions is reduced, and the stable and safe use of the flexible battery is ensured.
The adhesive layer 23 is provided on the opposite side of the barrier layer 22 from the rubber layer 21. The adhesive layer 23 has a barrier effect to prevent corrosive substances from damaging the barrier layer 22. The adhesive layer 23 also has an adhesive connection function, and the package housing 20 is bonded by the adhesive layer 23 to form a package cavity 25.
As for the connection mode of the adhesive layer 23 and the barrier layer 22, as shown in fig. 4, an adhesive layer 24 is provided between the adhesive layer 23 and the barrier layer 22, and the adhesive layer 23 is connected to the barrier layer 22 through the adhesive layer 24.
As for the material of the adhesive layer 23, as an example, the material of the adhesive layer 23 is a resin such as polyethylene, polypropylene, cast polypropylene (cast polypropylene, CPP), or the like.
As another example, the material of the adhesive layer 23 includes a rubber component. For example, the material of the adhesive layer 23 is a rubber/resin composite material. The rubber/resin composite material is prepared by taking rubber and resin as main components through a physical blending or graft blending process. Optionally, the rubber/resin composite further comprises components such as a coupling agent. The coupling agent is used for improving the interfacial properties of the rubber component and the resin component, and ensuring that the adhesive layer 23 has good mechanical properties and processability.
Optionally, the rubber component in the tie layer 23 includes at least one of: nitrile rubber, styrene butadiene rubber, isoprene rubber, neoprene rubber and fluororubber. The resin component in the adhesive layer 23 includes at least one of: polyethylene, polypropylene (including cast polypropylene). Of course, other resin components and rubber components may be used, and the embodiments of the present disclosure are not particularly limited.
In this way, the adhesive layer 23 of the rubber/resin composite material has better flexibility and deformability than the simple resin adhesive layer 23. Accordingly, the flexibility of the package housing 20 is further optimized, so that the deformability of the flexible battery is improved, and the stable and safe use of the flexible battery is ensured.
In one embodiment, as shown in fig. 5, the rubber layer 21 is located on the side of the barrier layer 22 facing away from the electrode assembly 10, i.e., the rubber layer 21 faces the outside of the encapsulation cavity 25. In this way, the rubber layer 21 plays an external protective role, so that the barrier layer 22 is protected from mechanical damage. In addition, the rubber layer 21 is also decorative, so that the appearance performance of the flexible battery is improved.
The adhesive layer 23 is located on the side of the barrier layer 22 facing the electrode assembly 10, i.e., the rubber layer 21 is located inside the encapsulation cavity 25. In this way, the barrier layer 22 and the electrolyte solution or other corrosive liquid within the package cavity 25 are isolated by the adhesive layer 23. Particularly in the case of flexible batteries that do not include an inner housing 14, corrosion of barrier layer 22 by the electrolyte is effectively avoided by adhesive layer 23.
The flexible battery provided by the embodiment of the disclosure improves the flexibility of the whole flexible battery and improves the deformation matching degree of the flexible battery and an external component by arranging the rubber layer 21 in the packaging shell 20. And the package case 20 is not easily broken during use, improving the stability and safety of the use of the flexible battery.
It should be noted that, in the embodiment of the present disclosure, the flexible battery may be applied to a wearable device (e.g., a bracelet, a watch, glasses, etc.), a mobile terminal (e.g., a mobile phone, a tablet computer, etc.) having a flexible screen or a curved screen, a vehicle-mounted device, or a medical device.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any adaptations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
