[0022] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0023] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0024] Batteries on electronic devices can be divided into single-cell batteries, dual-cell series batteries, and dual-cell parallel batteries according to the number of cells. Parallel batteries are generally used on folding screens; for conventional mobile phones, single-cell batteries or dual-cell series batteries are generally used.

[0025] As the charging wattage increases, the charging temperature rise of the whole machine becomes higher and higher. In order to reduce the charging temperature rise during the charging process, a dual-cell series connection method is usually adopted. Under the same charging wattage, thanks to the high voltage characteristics of the dual-cell series battery, the charging current of this type of battery is half of that of a single-cell battery, which can significantly reduce the temperature rise of the charging components, such as the temperature of the battery protection board and the temperature of the charging module on the whole machine.

[0026] The dual-cell series-connected batteries in the related art are all soft-pack structures. Figure 1 As shown, when the battery protection board 1 is connected to the battery cell, there need to be four connection positions of the electrode columns 2 on the protection board. The energy density of the dual-cell series battery is not as good as that of the single-cell battery. The battery in series is two soft-pack batteries connected in series side by side. Since the soft-pack batteries have a large tolerance in the width direction, the two soft-pack batteries are placed side by side in the width direction. The width tolerance of the battery will be larger, resulting in a larger battery volume, and more space will need to be reserved in the width on the electronic device. There are sealing areas of aluminum-plastic film on the two sides of the length direction of the soft-pack battery. This area occupies the volume of the battery cell and does not provide capacity; the dual-cell series battery has four such areas, which affects the capacity of the battery, resulting in a lower energy density and a larger volume of the battery.

[0027] Based on the above shortcomings, the present disclosure provides a battery, referring to Figure 2 As shown, the battery includes a connection circuit 4 and a first sub-battery and a second sub-battery.

[0028] The first sub-battery may include a first conductor shell 311 and a first battery cell 313, wherein the first sub-battery 31 includes the first conductor shell 311 and the first battery cell 313; the first battery cell 313 is disposed in the first conductor shell 311, and the negative electrode of the first battery cell 313 is connected to the first conductor shell 311; the second sub-battery 32 includes a second conductor shell 321 and a second battery cell 323, and the second conductor shell 321 is attached to the first conductor shell 311; the second battery cell 323 is disposed in the second conductor shell 321, and the positive electrode of the second battery cell 323 is connected to the second conductor shell 321; one end of the connection circuit is connected to the positive electrode of the first battery cell 313, and the other end is connected to the negative electrode of the second battery cell 323.

On the other hand, the use of the conductor outer shell eliminates the need to set an insulating layer between the first sub-battery 31 and the second sub-battery 32, which enhances the energy density of the battery. Under the condition of the same capacity, the volume of the battery can be reduced, which makes it easier to place the battery in smaller electronic devices, making the battery more widely used.

In the present example implementation, one end of the connection circuit may be connected to a pole of a first sub-battery among a plurality of even number of sub-batteries connected in sequence, and the other end may be connected to a pole of a last sub-battery among a plurality of even number of sub-batteries connected in sequence.

[0079] In this example embodiment, one end of the connecting circuit is connected to the pole of the first sub-battery among the sub-batteries connected in sequence, and the other end is connected to the pole of the last sub-battery among the sub-batteries connected in sequence. For example, if the above-mentioned battery includes two sub-batteries, namely a first sub-battery and a second sub-battery, the connecting circuit is connected to the first pole of the first sub-battery and the second pole of the second sub-battery. For another example, if the above-mentioned battery includes four sub-batteries, the above-mentioned connecting circuit is connected to the pole of the above-mentioned first sub-battery and the pole of the fourth sub-battery.

On the other hand, by using a conductor shell, there is no need to set an insulating layer between the first sub-battery and the second sub-battery, thereby enhancing the energy density of the battery. Under the condition of the same capacity, the volume of the battery can be reduced, and it is convenient to arrange the battery in a smaller electronic device, so that the battery has a wider range of use. On the other hand, using a metal material as the outer shell of the battery can enhance the strength of the battery and enhance its service life. On the other hand, the first sub-battery and the second sub-battery that are attached together are connected by a conductor connector 5, so that the connection is tighter, and a circuit break can be prevented between the sub-batteries. The electrical signal in the connection circuit can also be connected to the conductor connector 5, so that a single sub-battery can be detected, and the detection of the battery is enhanced, and damage to the electronic device caused by damage to a single sub-battery can be prevented. Furthermore, the first injection hole 314 and the second injection hole 324 may be covered with a conductor connector 5 to enhance the sealing effect of the injection holes and prevent the electrolyte from flowing out and causing damage to the battery.
