The outer cover 140 may also be connected to an external power supply device to charge the battery 100.
As shown in fig. 3 and 4, fig. 3 is a schematic structural diagram of a cell, a positive tab and a negative tab in the battery shown in fig. 2, and fig. 4 is a schematic structural diagram of a first cross section of the battery shown in fig. 2 along a P-P direction. The battery 100 may further include a battery cell 160, the battery cell 160 may be accommodated in the accommodating groove 122, and the battery cell 160 may be used to store electrical energy. The cell 160 may include a positive tab 161, a negative tab 162, a positive tab 163, and a negative tab 164.
The positive electrode sheet 161 is provided with a first connection point 1612, and the first connection point 1612 is located at one end of the positive electrode sheet 161. For example, the positive electrode tab 161 may have a rectangular sheet structure, the positive electrode tab 161 has two opposite ends, the two ends are two ends of the positive electrode tab 161 in the width direction, and the first connection point 1612 may be located at one end of the positive electrode tab 161 or at the other end of the positive electrode tab 161. The positive tab 161 is connected to the positive tab 163, and the positive tab 163 may be connected to the case 120 or the outer cover 140, so that the case 120 or the outer cover 140 may serve as a positive electrode of the battery 100.
As shown in fig. 4, the negative electrode tab 162 is disposed on one side of the positive electrode tab 161 at an interval. For example, negative electrode tab 162 may be separated from positive electrode tab 161 by a separator 165, where separator 165 is configured to prevent current from flowing directly from positive electrode tab 161 to negative electrode tab 162, thereby causing a short circuit. The separator 165 may be made of a microporous polyolefin film such as a polyethylene film or a polypropylene film. For safety, the separator 165 preferably has a function of blocking a micro pore (blocking pore) at 120 ℃ or more, so that the internal resistance is increased, thereby blocking current.
It is understood that when the positive electrode tab 161 and the negative electrode tab 162 are spaced apart from each other, one end of the positive electrode tab 161 is located on the same side as the first end 1622, and the other end of the positive electrode tab 161 is located on the same side as the second end 1624. When the first connection point 1612 is located at one end portion of the positive electrode tab 161, the second connection point 1626 is located near the first end portion 1622; when the first connection point 1612 is located at the other end of the positive electrode tab 161, the second connection point 1626 is located near the second end 1624, i.e., the first connection point 1612 and the second connection point 1626 are located at substantially the same position of the positive electrode tab 161 and the negative electrode tab 162, so that the direction of current flowing on the positive electrode tab 161 is opposite to the direction of current flowing on the negative electrode tab 162. At this time, the direction of the magnetic field generated by the current of the positive electrode tab 161 is opposite to the direction of the magnetic field generated by the current of the negative electrode tab 162.
As shown in fig. 4, the first portion 1621 is a portion of the second connection point 1626 to the second end 1624, and the second portion 1623 is a portion of the second connection point 1626 to the first end 1622. The length of the first portion 1621 is equal to the length of the positive electrode tab 161, so that the current flowing through the positive electrode tab 161 is equal to the current flowing through the negative electrode tab 162, the magnetic field strength generated by the current of the positive electrode tab 161 is equal to the magnetic field strength generated by the current of the negative electrode tab 162, and the magnetic field generated by the current of the positive electrode tab 161 and the magnetic field generated by the current of the negative electrode tab 162 are cancelled out, so that the magnetic interference signal generated by the battery 100 in the process of supplying electric energy is reduced, and the influence on the sound signal output by the speaker 200 can be reduced.
It is understood that the first portion 1621 of the negative electrode tab 162 is a portion of the negative electrode tab 162 that can be used to transmit a current signal, or can form a current loop with the positive electrode tab 161, and can be understood as an active portion, and the second portion 1623 is a portion of the negative electrode tab 162 that cannot transmit a current signal, and can be understood as an inactive portion.
The negative electrode tab 162 is connected to the negative electrode tab 164, and the negative electrode tab 164 may be connected to the casing 120 or the outer cover 140, so that the casing 120 or the outer cover 140 may serve as a negative electrode of the battery 100. It should be noted that positive tab 163 and negative tab 164 may also be connected to outer cover 140 at the same time, so that outer cover 140 may be used as both the positive and negative electrodes of battery 100 to output electrical energy or to perform charging. Alternatively, positive tab 163 and negative tab 164 may be connected to housing 120 at the same time, such that housing 120 may serve as both the positive and negative electrodes of battery 100.
With continued reference to fig. 4, the positive electrode sheet 161, the negative electrode sheet 162 and the separator 165 are wound, for example, the positive electrode sheet 161 and the negative electrode sheet 162 are wound into a cylindrical structure as shown in fig. 3, but the positive electrode sheet 161 and the negative electrode sheet 162 may also be wound into a rectangular parallelepiped structure, a cube structure or other three-dimensional structures. The positive electrode sheet 161 may be wound with one end of the positive electrode sheet 161 as a winding head, and after the winding, the other end of the positive electrode sheet 161 may be a winding end. It is understood that when the battery cell 160 is received in the receiving groove 122, the winding end of the positive electrode sheet 161 is the end of the positive electrode sheet 161 close to the groove wall of the receiving groove 122 (or the inner surface of the housing 120), and the winding head end of the positive electrode sheet 161 is the end of the positive electrode sheet 161 away from the groove wall of the receiving groove 122 (or the inner surface of the housing 120).
Referring to fig. 5 and 6, fig. 5 is a schematic diagram illustrating a first structure of the positive plate, the negative plate, the positive tab and the negative tab shown in fig. 4, and fig. 6 is a schematic diagram illustrating a second structure of the battery in the wireless headset shown in fig. 1. The first connection point 1612 may be located at a winding end of the positive electrode sheet 161 and the second connection point 1626 may be located on the first portion 1621 with the second connection point 1626 being closer to the first end 1622, or the winding end, than to the second end 1624. When the battery 100 supplies power to the outside, a current signal on the positive electrode sheet 161 flows from the winding end of the positive electrode sheet 161 to the winding head end of the positive electrode sheet 161, and the current flowing through the positive electrode sheet 161 generates a magnetic field from the outer cover 140 toward the bottom of the housing 120; the current signal on the negative pole piece 162 flows from the second end 1624 to the second connection 1626, i.e., the current flowing on the first portion 1621, and the current flowing through the first portion 1621 generates a magnetic field from the bottom of the housing 120 toward the outer cover 140, i.e., the magnetic fields of the two are opposite in direction. It is understood that first connection point 1612 and second connection point 1626 after winding are both located outside of cell 160, or positive tab 163 and negative tab 164 are both located outside of cell 160.
Since the length of the first portion 1621 is equal to the length of the positive electrode tab 161, the magnetic field strength (or magnetic flux) of the magnetic field generated by the current flowing through the negative electrode tab 162 is equal to the magnetic field strength (or magnetic flux) of the magnetic field generated by the current flowing through the positive electrode tab 161, so that the magnetic field generated by the current flowing through the negative electrode tab 162 and the magnetic field generated by the current flowing through the positive electrode tab 161 can cancel each other out, thereby reducing the magnetic interference signal generated by the battery 100 in the process of supplying power, reducing the influence on the sound signal output by the speaker 200, and improving the hearing experience of the user when using the wireless earphone 20.
As shown in fig. 4, the winding end of the positive electrode sheet 161 is located between the second connection point 1626 and the first end 1622 so that the second portion 1623 may enclose the winding end of the positive electrode sheet 161. It can be understood that the overall length of the negative electrode tab 162 is longer than the overall length of the positive electrode tab 161, and the winding end of the positive electrode tab 161 is completely wrapped, which can prevent the winding end of the positive electrode tab 161 from being directly exposed to the outside to cause current leakage of the battery 100, thereby improving the safety and reliability of the battery 100.
It should be noted that the structure of the negative electrode tab 162 is not limited thereto, and the arrangement positions of the first connection point 1612 and the second connection point 1626 are not limited thereto, for example, as shown in fig. 7, 8 and 9, fig. 7 is a schematic diagram of a second cross-sectional structure of the battery shown in fig. 2 along the P-P direction, fig. 8 is a schematic diagram of a first structure of the positive electrode tab, the negative electrode tab, the positive electrode tab and the negative electrode tab shown in fig. 7, and fig. 9 is a schematic diagram of a third structure of the battery in the wireless headset shown in fig. 1. First connection point 1612 may be located at the winding head end of positive plate 161 and second connection point 1626 is located between first end 1622 and second end 1624, and is closer to second end 1624, or the winding head end, relative to first end 1622. When the battery 100 supplies power to the outside, a current signal on the positive electrode sheet 161 flows from the winding head end of the positive electrode sheet 161 to the winding tail end of the positive electrode sheet 161, and the current flowing through the positive electrode sheet 161 generates a magnetic field from the bottom of the housing 120 toward the outer cover 140; the current signal on the negative pole piece 162 flows from the first end 1622 to the second connection 1626, i.e., the current flowing in the first portion 1621, and the current flowing in the first portion 1621 generates a magnetic field from the outer cover 140 toward the bottom of the housing 120, i.e., the magnetic fields of the two are opposite in direction. It is understood that first connection point 1612 and second connection point 1626 after winding are both located inside of cell 160, or positive tab 163 and negative tab 164 are both located inside of cell 160.
Wherein second end 1624 is flush with the winding head of positive plate 161, which facilitates the winding of positive plate 161 and negative plate 162.
With continued reference to fig. 3, the leading direction of the positive tab 163 is the same as the leading direction of the negative tab 164, for example, the positive tab 163 and the negative tab 164 are both led toward the housing 120, or the positive tab 163 and the negative tab 164 are both led toward the outer cover 140, and the length of the positive tab 163 is equal to the length of the negative tab 164.
The separator 165 in the embodiment of the present application may be impregnated with an electrolyte solution of a liquid electrolyte. The electrolyte solution includes, for example, a solvent and a lithium salt dissolved in the solvent to serve as an electrolytic salt, and may further include various additives as necessary.
